The magnitude of velocity for this car is equal to 1.5 m/s.
<u>Given the following data:</u>
To calculate the magnitude of velocity for this car:
<h3>What is momentum?</h3>In Science, momentum simply means a multiplication of the mass of an object and its velocity.
Mathematically, momentum is giving by the formula;
Making velocity the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Velocity = 1.5 m/s.

Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Explanation:
Formula to compute power:
Power = , I = cureent, R = resistance.
Given R = 5 ohm , Current = 0.5 A.
Then, power =
Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Answer:
65.9°
Explanation:
When light goes through air to glass
angle of incidence, i = 35°
refractive index, n = 1.5
Let r be the angle of refraction
Use Snell's law
Sin r = 0.382
r = 22.5°
Now the ray is incident on the glass surface.
A = r + r'
Where, r' be the angle of incidence at other surface
r' = 60° - 22.5° = 37.5°
Now use Snell's law at other surface
Where, i' be the angle at which the light exit from other surface.
Sin i' = 0.913
i' = 65.9°
