Answer:
The acceleration of the object is 
Explanation:
Given:
Initial velocity of object 
= 200 feet/second
Final velocity of object 
= 50 feet/second
Time of travel = 5 seconds
To calculate acceleration of the object we will find the rate of change of velocity with respect to time.
So, acceleration 
is given by:
where represents final velocity, represents initial velocity and 
is time of travel.
Plugging in values to evaluate acceleration.
The acceleration of the object is (Answer). The negative sign shows the object is slowing down.
Answer:
0 J
Explanation:
= Work done on the satellite in circular orbit about earth by earth
= Force on gravity on satellite by earth
= displacement of the satellite
= Angle between the force on gravity and displacement = 90
We know that, Work done is given as
The magnitude of the charge on the balloon is 1.6 x 10⁻¹² C.
<h3>
What is the magnitude of the charge on the ball?</h3>
The magnitude of the charge on the ball is calculated by determining the total charge equivalent to the given number of electrons.
The charge of one electron = 1.6 x 10⁻¹⁹ Coulombs
Now, we are going to estimated the total charge of 1 x 10⁷ electrons.
1 electron = 1.6 x 10⁻¹⁹ C
1 x 10⁷ electrons = ?
= (1 x 10⁷ electrons x 1.6 x 10⁻¹⁹ C) / (1 electron)
= 1.6 x 10⁻¹² C
Thus, the total charge of 1 x 10⁷ electrons is obtained by multiplying the magnitude of charge of one electron to the entire given electrons.

Answer:
P = 1333.33 N
Explanation:
The pressure exerted by the boy on the floor can be calculated by the following equation:
where,
P = Pressure exerted by the boy = ?
F = Force Applied = Weight of Boy = 40 kg = 40 N (since 1 kg = 1N)
A = Area of application of force = 2(Area of one show) = 2(6 cm x 25 cm)
A = 2(0.06 m x 0.25 m) = 0.03 m²
Therefore,
<u>P = 1333.33 N</u>
