Answer:</h2>
(a) 10.00V
(b) 0.5V
<h2>
Explanation:</h2>
(a) The power(P) supplied by a resistor of resistance (R) when a voltage(V) is passed across is given by;
P = V² / R ------------------(i)
From the question;
P = 5.00W
R = 20.00Ω
Substitute these values into equation (i) as follows;
5.00 = V² / 20.00
V² = 5.00 x 20.00
V² = 100.00
V = 
Solve for V;
V = 10.00V
Therefore, the maximum voltage that can be applied without harming the resistor is 10.00V
(b) By Ohm's law the current (I) flowing through a resistor of resistance (R) when a voltage (V) is applied is given by;
V = I x R
=> I = V / R ----------------(ii)
Substitute the values of V and R into equation (ii) as follows;
I = 10.00 / 20.00
I = 0.5A
Therefore, the current through the resistor is 0.5A

Answer:
<em>It takes 3 seconds to reach its high point</em>
Explanation:
<u>Projectile Motion</u>
In a projectile motion (or 2D motion), the object is launched with an initial angle θ and an initial velocity vo.
The components of the velocity are


The speed in the horizontal direction at any time t is:

The time taken to reach the maximum height is when vy=0, or:

We are given the y-component of the velocity, thus:


It takes 3 seconds to reach its high point
A strong magnetic field surrounds Earth and (C) It keeps the solar wind from reaching Earth. If all the particles of the solar wind contact the earth, they would make the ozone layer disappear. The ozone layer is the one in charge of protecting the earth from the ultraviolet radiation.
