Answer:
The maximum height reached by the ball is 2.84 m
Explanation:
Given;
initial velocity of the soccer, u = 13 m/s
angle of projection, θ = 35°
The maximum height reached by the ball = ?
Apply the following kinematic equation, to determine the maximum height reached by the ball.
Maximum height (H) is given as;

Therefore, the maximum height reached by the ball is 2.84 m
Answer:
a. The primary turns is 60 turns
b. The secondary voltage will be 360 volts.
Explanation:
Given data
secondary turns N2= 40 turns
primary turns N1= ?
primary voltage V1= 120 volts
secondary voltage V2= 8 volts
Applying the transformer formula which is

we can solve for N1 by substituting into the equation above

the primary turns is 60 turns
If the primary voltage is V1 240 volts hence the secondary voltage V2 will be (to get the voltage of the secondary coil using emf substitute the values of the previously gotten N1 and N2 using V1 as 240 volts)

the secondary voltage will be 360 volts.
Answer:
275 kPa
Explanation:
mass of the gas=m=1.5 kg
initial volume if the gas=V₁=0.04 m³
initial pressure of the gas= P₁=550 kPa
as the condition is given final volume is double the initial volume
V₂=final volume
V₂=2 V₁
As the temperature is constant
T₁=T₂=T
=
putting the values in the equation.
=
P₂=
P₂=
P₂=275 kPa
So the final pressure of the gas is 275 kPa.

<u>Answers</u>
1) 3,840 N
2) 80 m
<u>Explanations</u>
Centripetal force is the force that maintenance objects that are moving in a circular motion.
F = mv²/r
= (1500 × 16²)/100
= (1500×256)/100
= 384000/100
= 3,840 N
2) F = (mv²)/r
6000 N = (1200 × 20²)/r
r = (1200 × 400)/6000
= 480,000/6000
= 80 m
