A large sphere has a mass of 175 kg and is suspended by a chain from the ceiling. The mass of the chain is 12.0 kg. What is the tension in the chain?1830, N1610, N1720, N1940 N.

Answers

Answer 1

Answer:
Each point in the chain supports the weight of all the mass below it.

At the bottom end of the chain, the weight is (175 x 9.8) = 1,715 N .
At the top of the chain, the weight is (175 + 12) x (9.8) = 1,833 N .

The tension in the chain varies linearly from 1,715N at the bottom
to 1,833N at the top.

A wire that is 0.36 meters long moves perpendicularly through a magnetic field at a speed of 0.21 meters/second. The induced emf produced in the wire is 0.45 volts. What is the magnetic field strength?

Answers

Answer:

Magnetic field strength, B = 5.95 Tesla

Explanation:

It is given that,

Length of wire, l = 0.36 m

It is moving perpendicularly through a magnetic field at a speed of, v = 0.21 m/s

Induced emf, E = 0.45 volts

The mathematical expression for induced emf is given by :

$E=(d\phi)/(dt)=Blv$

$(d\phi)/(dt)$ is the rate of change of magnetic flux,

B is magnetic field

So, $B=(E)/(lv)$

$B=(0.45)/(0.36* 0.21)$

B = 5.95 Tesla

Hence, this is the required solution.

Scientists have observed that the average sunspots have increased in the last 50 years. Which of these statements best describes an effect of this increase in sunspots? A) Earth's temperature has become cooler.
B) Earth's temperature has not changed over time.
C) Earth's temperature has become warmer.
D) Earth's temperature has reduced by fifty times.

Answers

Answer:

Earth's temperature has become cooler

Explanation:

The number of sunspots, as you have learned, can indicate whether the sun is in a maximum-activity period or a minimum-activity period. Some scientists believe this can have an overall effect on the climate of Earth.

The right answer for the question that is being asked and shown above is that: "B) Earth's temperature has not changed over time." Scientists have observed that the average sunspots have increased in the last 50 years. The statement that best describes an effect of this increase in sunspots Earth's temperature has not changed over time.

A 2.50 × 105 W motor is used for 26.4 s to pull a boat straight toward shore. How far does the boat move toward shore if a force of 4.20 × 104 N is applied by the motor?

Answers

The power of the motor is
2.50x10⁵ W
or
2.50x10⁵ N m/s

The time it takes to pull the boat is
26.4 s

The force applied is
4.20x10⁴ N

The distance traveled by the boat is
2.50x10⁵ N m /s (26.4 s) / (4.20x10⁴ N)
= 157.14 m

Answer:

157 m
