Answer:

The Tension in the cable is 392.3N. The vertical reaction at the hinge (fixed end) is 850.3N.

The tension in the cable was calculated using the principles of moments which states that the total sum of the clockwise moments is equal to the total sum of anticlockwise moments on a system in equilibrium.

Explanation:

Sum of Clockwise moments = Sum of anticlockwise moments

900×1 + 200×3 + 90×6 = T×Sin120 × 6

900 + 600 + 540 = 5.20T

T = 2040/5.20 = 392.3N

Summing vertical forces

R + Tsin120 = 900 +200+90

R + 392.3sin120 = 1190

R + 339.7 = 1190

R = 1190 - 339.7

R = 850.3N

How can we protect space shuttles or astronauts from space radiation in the absence of the atmospheric layer?
antiseptic1488 [7]

Answer:

1. In general, the best shields will be able to block a spectrum of radiation. Aboard the space station, the use of hydrogen-rich shielding such as polyethylene in the most frequently occupied locations, such as the sleeping quarters and the galley, has reduced the crew's exposure to space radiation.

2. It absorbs harmful ultraviolet radiation from the sun, helps keep Earth's surface warm via the greenhouse effect, and reduces temperature extremes between day and night. ... So, thanks to gravity, although some of Earth's atmosphere is escaping to space, most is staying here.

hope it helps. please mark me as brainliest and follow me ❤️

What the name for the phenomenon of inducing voltage by changing the magnetic field around a conductor?
8090 [49]

The phenomenon of inducing voltage by changing the magnetic field around a conductor will be Electromagnetic Induction. Option B is correct.

<h3>What is the Faraday law of electromagnetic induction?</h3>

According to Faraday's law of electromagnetic induction, the rate of change of magnetic flux link with the coil is responsible for generating emf in the coil to result in the flow of amount of current .

So in order to increase the current, we need to increase the EMF;

so we can increase it by;

1) Increasing the number of turns

2) Increase the area of the loop

3) By moving the magnet faster

Hence, option B is correct.

To learn more about Faraday law of electromagnetic induction:

Two planets, Dean and Sam, orbit the Sun. They each have with circular orbits, but orbit at different distances from the Sun. De
lyudmila [28]

Answer:

The correct answer is Dean has a period greater than San

Explanation:

Kepler's third law is an application of Newton's second law where the force is the universal force of attraction for circular orbits, where it is obtained.

                T² = (4π² / G M)  r³

When applying this equation to our case, the planet with a greater orbit must have a greater period.

Consequently Dean must have a period greater than San which has the smallest orbit

The correct answer is Dean has a period greater than San
