Skater 1 has a mass of 45 kg and is at rest. Skater 2 has a mass of 50 kg and is moving slowly at a constant velocity of 3.2 m/s
algol13

Answer:

None

Explanation:

Force, F is given by ma where m is the mass of an object and a is acceleration

Acceleration is the rate of change in velocity per unit time. Since skaters with mass of 75 kg and 50 kg are moving at a constant speed, there is no acceleration hence F=50*0=0 and F=75*0=0

For skater of 45 kg, he is at rest to mean the initial and final velocitu of the skater is zero hence no acceleration, the force will be 45*0=0

Therefore, none of the skaters will experience a greater net force.

How are oceans connected to all bodies of water
inn [45]
Oceans are collected to all bodies of water because

- All Rivers, streams, or swamps end up flowing out into an ocean somehow
- The oceans are the largest bodies of water, so most of the water on earth comes from them, or has been in the oceans.

A 1 200-kg car traveling initially at vCi 5 25.0 m/s in an easterly direction crashes into the back of a 9 000-kg truck moving i
sukhopar [10]

Answer:

The velocity of the truck after the collision is 20.93 m/s

Explanation:

It is given that,

Mass of car, m₁ = 1200 kg

Initial velocity of the car, v_{Ci}=25\ m/s

Mass of truck, m₂ = 9000 kg

Initial velocity of the truck, v_{Ti}=20\ m/s

After the collision, velocity of the car, v_{Cf}=18\ m/s

Let v is the velocity of the truck immediately after the collision. The momentum of the system remains conversed.

initial\ momentum=final\ momentum

1200\ kg\times 25\ m/s+9000\ kg\times 20\ m/s=1200\ kg\times 18+9000\ kg\times v

210000-21600=9000\ kg\times v

v=20.93\ m/s

So, the velocity of the truck after the collision is 20.93 m/s. Hence, this is the required solution.

Earth's Moon is considered to be geologically dead because its interior has cooled considerably. Select the features of Earth th
DochEvi [55]

Answer:

The correct option is;

E. motion of tectonic plates.

Explanation:

The Moon is formed from the Earth, and so have similar composition. However, the smaller size of the moon as well as the low temperature of the Moon's mantle compared to the interior of the earth, contribute the state of the Moon having no active tectonic plate motion and no convection.

The convection in the mantle, drives Earth's tectonic plate motions. The mantle within Earth moves at a rate of some centimeters annually, while the Moon, geologically is a dying world.
