Here it is given that an elevator is moving down with an acceleration of 3.36 m/s² . And we are interested in finding out the apparent weight of a 64.2 kg man . For the diagram refer to the attachment .
- From the elevator's frame ( non inertial frame of reference) , we would have to think of a pseudo force.
- The direction of this force is opposite to the direction of acceleration the frame and its magnitude is equal to the product of mass of the concerned body with the acceleration of the frame .
- When a elevator accelerates down , the weight recorded is less than the actual weight .
From the Free body diagram ,
- Mass of the man = 64.2 kg
Answer:
The driving force behind plate tectonics is convection in the mantle. Hot material near the Earth's core rises, and colder mantle rock sinks. ... Geologists refer to the places where segments meet and divide as plate boundaries. They're thought to wrap around the Earth like seams on a baseball.
Explanation:
Hope this help!
<h3>
</h3><h3 /><h3>Scaler quantity ~</h3>
Physical quantities which needs only magnitude to express itself, and doesn't need any specific direction.
- it's calculations can be performed using simple algebraic methods
Example - Speed, Distance, time, mass, and so on.
<h3>Vector quantity ~</h3>
Physical quantities which needs magnitude as well as direction to express itself, and follows vector law of addition.
- It's calculations Can't be performed through simple algebraic methods, vector algebra is required.
Example - force, acceleration, velocity, and so on.
