A cart of mass m is pulled along a level dynamics track as shown above. A force sensor is attached to the cart with a string and
mart [117]

Answer:

  • <u>See the picture attached with the drawing of the forces.</u>

Explanation:

Find the figures with the question and the answer attached.

The answer shows the free body diagram with four arrows starting on, and pointing way from, the dot.

The red vertical upward arrow, labeled F_N, represents the normal force, which is the force exerted by the ground on the cart.

The red vertical downward arrow, labeled F_g, represents the gravity force (weight), which is the pull that the Earth exerts of the cart.

Both vertical arrows are of the same side because the normal force and the weight are balanced (since there is not vertical acceleration).

The blue horizontal arrow pointing to the right, labeled F_h, represents the horizontal pulling force exerted by the hand.

The blue horizontal arrow pointing to the left, labeled F_f, represents the frictional force which is not neglicible.

Since the cart is accelerating in the positive direction, toward the right,

F_h>F_f and the arrow to the right is larger than the arrow to the left.

What is the name of the warm phase associated with melting ice and higher sea level?
xenn [34]

Answer:

The combination of seawater's thermal expansion associated with this warming and the melting of mountain glaciers is predicted to lead to an increase in global sea level of 0.45-0.82 metre (1.4-2.7 feet) by 2100 under the RCP 8.5 emissions scenario. However, the actual rise in sea level could be considerably greater than this.
