Answer: The object moved 2 metres away
Explanation:
Given that the
Force applied F = 20 N
Work done W = 40 J
From the definition of workdone which state that: product of force and distance
W.D = F × S
Where S = distance
S = W.D/F
S = 40/20 = 2 metres
The object moved 2 metres away.
Answer:
The force by which a substance (magnet) attracts a body(metals) towards it is called magnetic force
Answer:
See explanation
Explanation:
The conversion factor from miles per hour to kilometers per hour is 1.609344.
Hence;
To convert 75mi/h to kilometers per hour,
75mi/h * 1.609344 = 120.7 kilometers per hour
b)
To convert 75mi/h to feet per second
Since
1 mile per hour = 1.46667 foot per second
75mi/h = 75 * 1.46667 = 110 feet per second
Answer:
1.5F
Explanation:
Using
E= F/q
Where F= force
E= electric field
q=charge
F= Eq
So if qis tripled and E is halved we have
F= (E/2)3q
F= 1.5Eq=>> 1.5F
