The watts determine the brightness. Watt is the unit of Power. And Power is equal to Voltage x Amps (current). So both the current and voltage determine the brightness.
Answer:
42.3 MV
Explanation:
d = diameter of the metal sphere = 2.15 m
r = radius of the metal sphere
diameter of the metal sphere is given as
d = 2r
2.15 = 2 r
r = 1.075 m
Q = charge on sphere = 5.05 mC = 5.05 x 10⁻³ C
Potential near the surface is given as


V = 4.23 x 10⁷ volts
V = 42.3 MV
Force applied = F = 628 N
<span>Acceleration = a m/s² </span>

<span>New mass of the crate = M1 = 3.8M kg </span>
<span>New acceleration = a1 = F/M1 = F/(3.8 M) ----- (2) </span>
<span>a1/a = {F/(3.8M)}/(F/M) = 1/3.8 = 10/38 = 5/19 ------- Answer</span>
Answer:
Break down small pebbles and sediments, like sand
Break down large rocks like mountains
Explanation:
The force applied by the student is 75 N
Explanation:
We can solve this problem by using Newton's second law, which states that the force applied on an object is equal to the product between the mass of the object and its acceleration:

where
F is the force applied
m is the mass of the object
a is the acceleration
In this problem,
m = 50 kg

Substituting, we find the force applied by the student:
