If we drop 2 objects of different weights from the same height, which one will reach the ground faster?
If we drop 2 objects of different weights from the same height, both of them will reach the ground at the same time.
Gravity, at the surface of a body like Earth, provides an acceleration to bodies and this acceleration is constant and its value is equal to 9.8m/s². This is because the Earth attracts big objects more than little ones, but the big ones have more inertia, which cancels out. So, all the bodies on the earth's surface fall at the same acceleration of 9.8m/s²
This acceleration due to gravity,g is independent of the mass of the body. The time of flight for any freely falling object depends on the value of acceleration due to gravity and its initial speed. So both the bodies reach the ground at the same time.

A skater is standing still on a frictionless ice rink. Her friend throws a Frisbee straight to her. In which of the following cases is the largest momentum transferred to the skater?
(a) The skater catches the Frisbee and holds onto it.
(b) The skater catches the Frisbee momentarily, but then drops it vertically downward.
(c) The skater catches the Frisbee, holds it momentarily, and throws it back to her friend.
The largest momentum transferred to the skater is the skater catches the Frisbee, holds it momentarily, and throws it back to her friend.
The skater stands on a frictionless surface and his friend Frisbee starts moving behind him. The lack of friction makes the skater unstoppable.
However, when the skater returns to his friend through the Frisbee again, there is a backward force that increases the skater's speed. So and momentum is directly proportional to velocity, so as velocity increases so does momentum.
In Newtonian mechanics, momentum (more precisely, linear or translational momentum) is the product of an object's mass and velocity. A vector quantity that has magnitude and direction. If m is the object's mass and v is its velocity (which is also a vector quantity), then the object's momentum p is p = mv.
Advanced formulations of classical, Lagrangian and Hamiltonian mechanics allow the choice of coordinate systems containing symmetries and constraints. In these systems the conserved quantity is the generalized momentum, which is generally different from the momentum defined above. The generalized concept of momentum carries over into quantum mechanics and becomes the operator of the wavefunction. The momentum and position operators are related by the Heisenberg uncertainty principle.

which of the following best accounts for the pressure in teh vessel remaining constant as the volume decreaseds betlow 0.21l
The best option that accounts for the pressure remaining constant in the vessel as the volume decreases below 0.21L is the ideal gas law PV = nRT
Support your answer with an explanation.According to the ideal gas law, the ratio of a gas's pressure (P) and volume (V) to its moles (n) multiplied by its gas constant (R) multiplied by its temperature (T) is known as the ideal gas equation. The pressure and volume are inversely related when the number of moles and the temperature are held constant, which means that as the volume falls, the pressure increases and vice versa.
However, in this case, as the volume falls below 0.21L, the pressure inside the vessel stays constant. This could be explained by the use of outside forces, such a membrane or a piston, which can keep the gas under pressure even as it decreases.

A car accelerates uniformly from rest and reaches a speed of 33.8 m/s in 4.7s the diameter of the tire is 64.6 cm find the number of revolutions the tire makes during this motion
The tire makes approximately 280.57 revolutions during this motion.
What are the revolutions?Generally, To find the number of revolutions the tire makes during this motion, we first need to find the distance traveled by the car.
Distance = Initial velocity x time + (1/2) x acceleration x time^2
Since the car starts at rest, the initial velocity is 0 m/s.
The acceleration is uniform, so we can use the formula:
Final velocity = Initial velocity + acceleration x time
In this case, the final velocity is 33.8 m/s, and the time is 4.7s.
So, acceleration = (33.8 m/s - 0 m/s) / 4.7s
= 7.19 m/s^2
Now we can use this value of acceleration to find the distance traveled:
Distance = 0 m/s x 4.7s + (1/2) x 7.19 m/s^2 x (4.7s)^2
= 570.98 m
To find the number of revolutions of the tire, we divide the distance traveled by the circumference of the tire.
The circumference of the tire is equal to the diameter x pi.
Circumference = 64.6 cm x 3.14
= 203.5 cm
Number of revolutions = Distance / Circumference

What is the kinetic energy of a 1,678-kilogram boat moving at 4.6 m
Answer:
17,753.24 J (Joules)
Explanation:
To calculate the kinetic energy of an object, we use the formula:
Kinetic energy = 1/2 * mass * velocity^2
where mass is measured in kilograms and velocity is measured in meters per second.
Given that the boat has a mass of 1,678 kilograms and a velocity of 4.6 meters per second, we can substitute these values into the formula to find its kinetic energy:
Kinetic energy = 1/2 * 1,678 * (4.6)^2
Kinetic energy = 1/2 * 1,678 * 21.16
Kinetic energy = 17,753.24 J (Joules)
So the kinetic energy of the 1,678-kilogram boat moving at 4.6 m/s is 17,753.24 J (Joules).

Suppose exactly 6.95 g of each reactant is taken and the following details are given by A and B then 6.95 g of A is equivalent to 6.95/molar mass of A moles of A. 6.95 g of B is equivalent to 6.95/molar mass of B moles of B.
How much extra reagent will still be present once the limiting reactant has been used up?To determine which reactant is limiting, we need to compare the amount of each reactant to the stoichiometry of the reaction.
The stoichiometry of the reaction is 1:2 for reactants A and B, respectively.
Therefore, if we have 6.95 g of A and 6.95 g of B, we can calculate the ratio of A to B to determine which reactant is limiting.
6.95 g of A is equivalent to 6.95/molar mass of A moles of A.
6.95 g of B is equivalent to 6.95/molar mass of B moles of B.
Comparing the moles of A and moles of B, we can see that A is limiting, as there is less A than required by the stoichiometry of the reaction.
To determine the mass of the excess reagent (B) that will remain after the limiting reactant (A) is consumed, we need to calculate the moles of B that are in excess.
We can calculate the moles of B that are used up by the reaction (based on the stoichiometry of the reaction) and subtract this from the total moles of B that were initially present.
The remaining moles of B can then be converted back into grams to find the mass of B that will remain.
Using the above method, the mass of the B remaining after A is consumed can be calculated.

What is mean by acceleration? The rate at which an object's velocity alters over time is called its acceleration. It has both magnitude and direction because it is a vector quantity. The difference between the change in velocity and the change in time is known as acceleration. In physics, acceleration is the rate of change of velocity with respect to time. It is measured in meters per second squared (m/s2). Acceleration is a vector quantity and is therefore described by both the magnitude and direction of the change in velocity. In everyday terms, acceleration is the rate at which an object speeds up, slows down or changes direction.

A collision at 30 mph will take any loose object in your car and give it the same force as if it were: shot from a canon.
What is the force of impact at 30 mph?Your body weight times the speed of the moving object equals the crash force. If you are holding your child while driving, you run the risk of crushing them if there is an accident. A 100-pound adult becomes a 3,000-pound force on the youngster in an accident at 30 miles per hour.About 40% of those struck by a car traveling at 30 mph will die as a result of their injuries, according to the U.S. Department of Transportation (DOT).

What is spring constant?"spring constant" (plural: "spring constants") a property of a spring that is determined by the force acting on the spring to the displacement it produces. The stiffness of the spring is quantified by the spring constant, k. For various materials and springs, it varies. The spring becomes stiffer and more challenging to stretch as the spring constant increases.
Given that,
mass (m) = 0.30 kg
distance (x) = 2.0 cm. = 2 × 10⁻² m
Thus, for balancing condition,
kx = mg
or, k = mg /x
or, k = (0.30 × 10) / (2 × 10⁻²)
or, k = 150 N/m
So, the value of spring constant is 150 N/m
Next, time period (T) = 2π √(m /k)
or, T = 2π √(0.30 / 150)
or, T = 0.2808 sec
Total stretches in spring constant = 2 cm + 1.5 cm = 3.5 cm
Total mechanical energy = 1/2 k x²
Total mechanical energy = 1/2 × (150) × (2 × 10⁻²)²
Total mechanical energy = 0.09187 Joule
