Answer:
A pendulum is weight suspended from a pivot so that it can swing freely
Answer:
If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before.
Answer:
<h3>The answer is 13.75 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question we have

We have the final answer as
<h3>13.75 m/s²</h3>
Hope this helps you
There’s no picture and what’s the length?
Answer:
P =105.44 W
Explanation:
Given that
D= 10 cm ,L= 60 cm
d= 0.1 cm ,B= 6.4 mT
ρ= 1.7 x 10⁻⁸ Ω · m
The number of turns N
N= L/d
N= 60/0.1 = 600 turns
Length of wire
Lc= πDN
Lc= 3.14 x 0.1 x 600
Lc=188.4 m
The magnetic filed given as


Now by putting the values

I=5.09 A
The resistance R given as




R=4.07 Ω
Power P
p =I²R
P= 5.09² x 4.07 W
P =105.44 W
