Answer: 95.7 N
Explanation: The tension on the chandelier is equal to the its weight.
Weight is the force directed downwards and tension is the force exerted of the opposite side.
T = W of the chain + W of the chandelier
= m1( g) + m2 (g)
= 0.37 kg ( 9.8 m/s2) + 9.4 kg (9.8 m/s2)
= - 95.7 N it means the force is directed downwards
since tension is equal weight
T = 95.7 N
She is going 66 miles per hour.
As you know, speed is usually measured in miles per hour. The distance between the 88 mile marker and the 121 mile marker is 33 miles. That means Sara’s mom travelled 33 miles in 30 mins. You want to figure out how many miles she travelled in 60 minutes.
If she travelled 33 miles in 30 minutes, and 60 minutes is double 30 minutes, then Sara’s mom was traveling 66 miles per hour.
Going out to a movie will not resolve the problem.
Increasing ambient temperature decreases efficiency and load carrying capacity of electric transmission lines.
Increased molecular movement in the conductors as temperature rises, increases resistance to current flow.
Answer:
a. The thickness of the wire is 2.5 mm.
b. The wire is 0.25 cm thick.
Explanation:
Number of turns of the wire = 10
The length of total turns = 25 mm
a. The thickness of the wire can be determined by;
thickness of the wire = 
= 
= 2.5 mm
Therefore, the wire is 2.5 mm thick.
b. To determine the thickness of the wire in centimetre;
10 mm = 1 cm
So that,
2.5 mm = x
x = 
= 0.25 cm
The wire is 0.25 cm thick.
