The forces that push upward on an indoor skydiver are lift force and air resistance.
The forces that act on a skydiver moving downwards includes, gravity due to his weight, air resistance and lift force.
The downward forces on the indoor skydiver include the following;
- <em>gravity due to its weight</em>
- <em>downward force due its acceleration</em>
<em />
The upward force on the indoor skydiver include the following;
- <em>lift force</em>
- <em>air resistance</em>
Thus, we can conclude that the forces that push upward on an indoor skydiver are lift force and air resistance.

The major water body given access to the new states of Kentucky and tennessee was the Mississippi river.
<u>Explanation:</u>
The Mississippi river serves to be the <em>second ranked</em> longest river located in the North America. the access was given to United States by the Kentucky state and Tennessee state.

The Mississippi river have been often remarked as the super highway to the sea. <em>Irrigation of crops with the transportation aid along with the food availability</em>, all calls for the grant access to the major water body.
Answer:
Explanation:
Given
Initially A moves towards Y axis with a velocity of 2 m/s and B moves towards X axis with velocity of 3.7 m/s
mass of both the block is same let say m
Conserving momentum in x direction
thus A moves with a velocity of 3.7 m/s towards x axis in order to conserve the momentum in x direction
Thus ball B moves towards Y direction with
And ball A moves towards X direction with
(c)Total momentum
Kinetic Energy
Answer:
E =9525.6 J
Explanation:
Given that
Current ,I = 4.9 A
time ,t = 5.4 min
Voltage difference ,ΔV = 6 V
energy delivered by battery in time t is given as
E=V I t
where V is voltage, I is the current and t is the time.
now putting the values in above equation
E= 6 x 4.9 x 5.4 x 60 J ( 1 min = 60 s , 5.4 min = 5.4 x 60 s)
E =9525.6 J
Therefore the energy reduced will be 9525.6 J
