The ball was rolling at a speed of 0.66 m/s when it was rolling on the desk.

Determine the time it takes the ball to fall  to the floor.

We have,

y = 0.70 m

g = 9.8 m/s²

s = 0.25 m

So,

y = ½ (a) (t)²

t = √(2y/g)

= √(2) (0.70 m) / (9.8 m/s²)

= 0.378 s

Determine the speed at which the ball rolls across the table.

v = s/t

= 0.25/0.378

= 0.66 m/s

Thus, the ball rolls off the table at a speed of 0.66 m/s

The current passing through the bulb having a voltage of 24 V is 9.6 Amperes

The potential difference of the bulb = 24 V

The resistance of the bulb = 2.5 ohms

The current flowing through the bulb can be found using ohm's law i.e.

                     I = V / R
where I is the current flowing through the bulb

          V is the potential difference in the bulb

          R is the resistance in the bulb

Let us substitute the known values in the above equation, we get

                  I = 24 / 2.5

                    = 9.6 A

Acceleration due to gravity is defined as the acceleration produced in a falling body due to the force of gravity. It is denoted by “g” and its value is 9.8m/(sec*sec).

The value of “g” does not depend on the mass of the falling body, it means if two objects say a cotton ball of mass 100 gram and an iron ball of mass 100 gram are allowed to fall in a vacuum tube (free from air resistance) from some height, then both the objects will hit the ground at the same time because both get accelerated towards the ground with the same acceleration i.e 9.8 m/ (sec*sec).

In simple words, 9.8 m/(sec*sec) means the velocity of a falling body increases by 9.8 m/sec after every I sec.

Thanks.

Answer: The formula for acceleration due to gravity is F=mg

Explanation: Where F stands for the force acting on the body and m stands for the mass of the body g is the acceleration due to gravity

The density of ice is less than that of water. So, ice floats on water. If the ice is floating on the surface of water the volume of ice submerged in the water will be equal to the volume of water displaced by the ice cube.

If a piece or cube of ice is placed in a container containing water, some of its portion will remain out of the water level. As we know the fact that, the volume of ice is greater than that of the water so after melting the volume of the piece will decrease and the water level will remain the same.

So, here the water level will remain the same when the ice cube will melt. Also, Stated by Archimedes that a floating object displaces an amount of water equal to its own weight. So as the water expands when it freezes, one ounce of frozen water has a larger volume than one ounce of liquid water.

Here, the apparent weight of the ice is equal to the weight of displaced water. When the ice will melt, it will occupy the volume of displaced water. So, water remains at the same level, as it was on before. It can also be said that the density of water is more than that of ice or vice versa, so the volume of water or the water level remains the same.

Using the concepts of work, we got that 0 joule is the amount of the work done during the process in which 1.2-m3 rigid tank contains nitrogen gas at 200 kpa and 350 k and heat is transferred to the nitrogen in the tank and the pressure of nitrogen rises to 900 kpa.

We are given some values of the rigid tank which are

Volume of the tank (V) = 1.2 m³

Initial pressure of the nitrogen (P₁) = 200 kPa

Initial temperature of the nitrogen (T₁) = 350 K

Final pressure of the nitrogen (P₂) = 900 kPa

The volume of nitrogen gas is same as volume of tank. Now, as the tank is rigid so, the volume of nitrogen gas remains the same.

We know that,

Work done on a gas is given as: PΔV

Where, ΔV is the change in volume.

But, the volume here is constant. So, ΔV = 0.

Therefore, work done=P×0=0Joules.

Hence, if 1. 2-m3 rigid tank contains nitrogen gas at 200 kpa and 350 k and  Heat is transferred to the nitrogen in the tank and the pressure of nitrogen rises to 900 kpa, then  the work done during this process is 0 joules.

Cold water does not react with iron. Iron, however, interacts with steam to create iron and hydrogen oxide. Fe3O4 + 4H2 = 3Fe(s) + 4H2O. Iron (II, III) oxide, also known as ferric oxide (Fe3O4), is a combination of Fe O and Fe2O3.

Ferric oxide (Fe2O3) and hydrogen gas are produced when ferrous oxide (Fe O) and water (H2O) combine (H2). This reaction yields a black solid called Fe3O4, which is frequently used as an antirust pigment. Understanding the chemical equation for this reaction is required to determine whether a specific mixture will produce Fe3O4: 2Fe3+(aq)+3H2 = 2Fe(s)+3H2(g) (g). According to this equation, two moles of iron metal will interact with to create two moles of ferric ion and three moles of hydrogen gas, it takes three moles of hydrogen gas. All of the iron will be transformed to Fe3+ ions and no Fe3O4 will occur if the combination only contains one mole of each component.

Using the concepts of Moment of inertia, we got that  2.43kgm²  is the moment of inertia of a  1. 5-kg-rod that rotates about its center if the length of the rod is 1. 8 m.

We know very well that moment of inertia of rod is different at different point.

Moment of inertia of rod about the center is given by (1/2)ML²,where moment of inertia of rod at the ends is given by (1/3)ML².

Now, we have mass of rod which is given by 1.5 kg, and length of rod is 1.8m

Therefore, moment of inertia of a rod about its center=(1/2)ML².

On putting the values,(M.O.I)=(1/2)×1.5×(1.8)×(1.8)

                                   =>(M.O.I)=(0.5)×1.5×1.8×1.8

Answer: 6.083N at  -80.538 degrees

Explanation:

Force is a vector so there is magnitude and direction

1. Find the net force in each direction.

net force (y) = everything up (positive y direction) - everything down (negative y)

= 9-3 = 6N

net force (x) = everything right - everything left

= 5-6 = -1N

These are the components of the net force on the object.

r = <-1, 6>

r is the vector of the force.

We can find magnitude by using the Pythagorean theorem.

sqrt( 1^2 + 6^2) = sqrt 37 or 6.083N

to find the direction we can use trig identities

tan(theta) = y/x

tan^-1 (y/x) = theta

tan^-1(6/-1) = -80.538 degrees.

The angular acceleration of the body is 9059.125 rad.

Angular Acceleration is described as the time rate of alternate angular velocity. it's also expressed in radians per 2d consistent with the second. accordingly, α = d ω d t. Angular acceleration is also called rotational acceleration.

Calculation:-

a. angular acceleration = change in angular velocity

a = 2π (1700 - 200)/60.115

  = 1.37 rad/sec²

b. θ = 01/2at²

      = 0.5×1.37 ×(115)²

      = 9059.125 rad.

Angular acceleration (α) can be described as angular velocity (ω) divided by acceleration time (t). rather, pi (π) increased by means of power pace (n) divided by acceleration time (t) multiplied by 30.

K is the spring constant.

If the spring is stretched by a distance of a then the potential energy of the mass spring system,

Starting at rest, a block accelerates at 4.0 meters per second square and slides down an 18-meter plank. The block needs three seconds to get to the bottom.

What is acceleration?

Acceleration is the term used to describe how quickly an object changes its velocity. A vector quantity is an acceleration. An object is said to be accelerating if its velocity is changing; an item with a steady velocity is not accelerating.

The velocity of a moving object refers to how quickly it is moving in that direction. Consider the speed of a car driving north on a highway or the speed at which a rocket takes off as an example.
Given that in the question block slides down an 18 m plank length with an acceleration of 4.0 meters per second square when it begins at rest.

Using the equation of motion,

S = ut + (1/2)at²

s is distance, s = 18 m

u is initial velocity, u = 0

a is acceleration, a = 4 m/sec²

t is time

18 = 0*t + (1/2)*4*t
