What is the work done by a force equivalent to the weight of 100, k, g,100kg that moves an object 200, k, m,200km in 7, point, 0, m, i, n,7. 0min?.

Answers

Answer 1

Using the concepts of work, we got that 7000 joules is the work done by a force equivalent to the weight of 100, k, g,100kg that moves an object 200, k, m,200km in 7, point, 0, m, i, n,7. 0min.

We know very well that if we want to move any object by a certain distance then we need to do some work so that it can moves against the frictional force.

We have

The mass of an object = 100 kg

But, Force = mass × g (taking g as 10 N/kg)

Then, Force = 1000 N

Assuming we are given the distance moved by the object as 7 m

We can calculate the work done by the force

We need to know that;

Work done = Force × distance

Therefore;

Work done = 1000 N × 7 m

                  = 7000 Joules(since 1Nm=1 Joule)

Hence, the work done by a force equivalent to the weight of 100, k, g,100kg that moves an object 200, k, m,200km in 7, point, 0, m, i, n,7. 0min is 7000 Joules.

Explanation:

kinetic energy = ½mv²

where v is speed and speed is 4.31 m/s,

½×m×(4.31)² = 106

(1)m×(4.31)² = 106×2

(2)m = (106×2) ÷ (4.31)² = 11.41251393 ≈ 11.4 kg

further details

(1)multiply 2 on both sides if the equation to remove the ½

(2)divide both sides by 4.31² to remove 4.31² from the mass

In mechanics, acceleration refers to the rate at which an object's velocity with respect to time varies. Acceleration is a vector quantity (in that they have magnitude and direction). The direction of an object's acceleration is determined by the direction of the net force acting on it.

According to Newton's Second Law, the amount of an object's acceleration is the combined result of two causes:  

1)The amount of the net resultant force, which is directly proportional to the sum of all external forces acting on that object;  2)Depending on the materials used to create it, an object's mass is inversely related to its magnitude.

Answers

The balloon volume is fixed at 0.413793. We can assume that the outside air pressure is constant.

The pressure inside a hot air balloon is affected by temperature. As the molecules heat up they move faster and hit the inner wall of the balloon harder. This increased motion of gas particles increases the force exerted on the area of the balloon increasing the pressure.

Calculation:-

Pressure = 120 kpa

Temperature = 290 K

PV = nRT

V = nRT/P

= 1 × 8.314× 290/120×100

= 0.413793

The frozen balloon contracted because the average kinetic energy of the gas molecules inside the balloon decreased as the temperature decreased.

El niño is a weather event that causes great changes in weather worldwide. During an el niño event, the polar jet stream shifts northward. Which change will an el niño event most likely cause?.

Answers

El niño affects the pattern of rainfall over months to seasons by redistributing heat and wind across the Pacific. As the atmosphere above the heated water surface warms, moist air rises and forms rain clouds.

Surface waters in the central and eastern Pacific Ocean become significantly warmer than usual during an El niño event. This shift is inextricably linked to the atmosphere and the winds blowing across the vast Pacific. Easterly trade winds (which blow from the Americas to Asia) weaken and can even turn westward. This allows large amounts of warm water to slosh from the western Pacific toward the Americas. It also reduces the upwelling of cooler, nutrient-rich waters from the deep, slowing or reversing ocean currents along the equator and the west coasts of South and Central America.

The air circulation above the tropical Pacific Ocean responds to this massive redistribution of ocean heat. The eastern Pacific's typically strong high-pressure systems weaken, altering the balance of atmospheric pressure across the eastern, central, and western Pacific. While easterly winds are typically dry and consistent, Pacific westerlies tend to arrive in bursts of warmer, moister air.

What is force ?

Mechanics compels any action intended to maintain, alter, or distort the motion of an object. The concept of force is commonly explained using Isaac Newton's three laws of motion. According to Newton's first principles, an object at rest, or in uniform linear motion, will remain in that state until a force is applied. The second law states that when an external force acts on an object, it will accelerate (change in velocity) in the direction of the force. The magnitude of acceleration is directly proportional to the magnitude of the external force and inversely proportional to the amount of matter in the body. Newton's third law states that when one object exerts a force on another object, the second object exerts the same force on the first object. This principle of action and reaction explains why forces tend to deform objects (that is, change their shape), whether or not they move them. Object deformation can usually be ignored when studying object motion.

Answers

The height of the cliff is 104.59 m.

Solution:

Time (t) = 4.62 s

Acceleration due to gravity (g) = 9.8 m/s²

Height (h) =?

h = ½gt²

h = ½ × 9.8 × 4.62²

h = 4.9 × 21.3444

h = 104.59 m

Thus, the height of the cliff is 104.59 m

The maximum point of the parabolic trajectory has a completely horizontal component. Since the velocity is only along the horizontal path, we can conclude that the horizontal velocity at the peak of the motion is zero. The initial horizontal velocity can also be determined by measuring the diameter d of the sphere and dividing it by the time t it takes for the sphere to move across the photogate.

Based on the nasa institute for space studies climate model, observed temperature increases are best represented when it includes the influences of?.

Answers

Observed temperature increases are best represented when it includes the influences of increases in greenhouse gases.

What are greenhouse gases ?

Greenhouse gases are gases in the atmosphere that affect the earth's energy balance. They cause the so-called greenhouse effect. Carbon dioxide (CO2), methane, and nitrous oxide, the best-known greenhouse gases, occur naturally in the atmosphere at low concentrations. However, since the beginning of the last century, its proportion has increased significantly due to various anthropogenic causes.

Besides these trace gases, which occur only in very low concentrations in the atmosphere, water vapor is probably the most important greenhouse gas. However, its ability to absorb water vapor from the air is directly related to temperature, so it only plays a major role with respect to the natural greenhouse effect. Therefore, water vapor contributes little to man-made climate change.
