A 5 kg object near Earth's surface is released from rest such that it falls a distance of 10 m. After the object falls 10 m, it

Answer:

R=V/I=6/2=3 ohm

time = 5 minutes = 5*60=300 seconds

I=2 A

Energy = I²Rt=(2)²*3*300=4*900=3600 J

As the parachutist is descending at a steady rate

we can conclude that

Acceleration indicates the change in velocity

given the constant velocity in this scenario

Thus, in this situation, we find the acceleration to be zero

It’s understood from Newton's second law

where a is equal to 0

Here, the force due to gravity

Hence, we can deduce

therefore

as such the upward force is counteracted by the downward force.

Answer:

Option b. it has the same position and the same acceleration as A

Explanation:

Now, let's examine each statement:

a. it has the same position and the same velocity as A

At the moment B overtakes A, they share the same location. However, their velocities cannot match, or else ball B wouldn't be able to pass ball A. Thus, this statement is false.

b. it has the same position and the same acceleration as A

As established before, their positions coincide, and both balls are subjected to gravitational acceleration, making this statement true.

c. it has the same velocity and the same acceleration as A

While the accelerations are identical, their velocities differ, rendering this statement false.

d. it has the same displacement and the same velocity as A

Though they have traveled the same distance, their velocities are not the same, thus this statement is false.

e. it has the same position, displacement and velocity as A

While their position and displacement match, their velocities do not, so this statement is false.

Therefore, only option b is correct.

Infiltration

Explanation:

The feature of the hydrologic cycle most impacted by impervious surfaces like concrete and asphalt is infiltration.

• Infiltration is crucial within the hydrologic cycle.
• Concrete and similar materials hinder water absorption into the ground.
• This adversely affects existing groundwater systems.
• A rise in surface runoff can occur, leading to potential flooding.
• Infiltration plays a pivotal role in the water cycle.
• It supplies water to plant roots and replenishes groundwater reserves.
• Impervious surfaces disrupt this natural process.
