Answer:
5
Explanation:
Formula for Mass (for this question)
mass= 1000N/200
=5
(pls do correct me if I have any mistakes it would rlly help others!)
Downward force of magnitude 5 N is exerted on the book by the force of <em>gravity</em>. We call that the "weight" of the book.
At the same time, upward force of 5 N is exerted on the book by the table. This one is called the "normal force".
Since the vertical forces on the book are 'balanced' (add up to zero), the book just lays there on the table, and does not accelerate.
Answer:
75
Explanation:
Power is current times voltage:
P = IV
Voltage is current times resistance:
V = IR
Therefore:
P = I²R
Given I = 0.62 A and R = 195 Ω:
P = (0.62 A)² (195 Ω)
P ≈ 75 W
<u>Given;</u>
mass m = 75 kg
acceleration a = 24.5 ms²
<em>F = ma </em>
F = 75 kg * 24.5 ms²
= 1837.5 kg ms².
