Answer:
2.7ohms
Explanation:
Given parameters:
Voltage of the battery = 12V
Current = 4.5A
Unknown:
Resistance of the resistor = ?
Solution:
From Ohm's law, we know that;
V = IR
V is the voltage
I is the current
R is the resistance
So;
R =
=
= 2.7ohms
Answer:
The duration of the impact is 0.005384 seconds
Explanation:
Given
m = 0.43 kg
v = 5.2 m/s
x = 0.014 m
Knowing the formulas

C a meter stick with only centimeters
D a ruler with millimeters and centimeters
D would be to the nearest half milimeter. Take some time to measure with a 2 inch ruler. Would you really need to know the length to half a mil ?
Answer:
F = [MLT⁻²]
Explanation:
Force = ma
m (mass) = [M]
a (acceleration) = [LT⁻²]
F(force) = m x a = [MLT⁻²]
