A 62 kg astronaut is space-walking outside the space capsule and is stationary when the tether line breaks. As a means of return

ing to the capsule, he throws his 3.3 kg wrench at a speed of 20.5 m/s away from the capsule. At what speed does the astronaut move toward the capsule

To solve this problem we must apply the concepts related to the conservation of momentum. We have the two masses of the bodies and the velocity of one of those bodies. Therefore, the initial momentum is equivalent to the final momentum. Mathematically this can be expressed as

P_i = P_f

m_1_v_1 = m_2 v_2

Replacing with our values,

3.3kg(20.5m/s) = (62kg)v_2

Solving for v_2,

v_2= 1.09m/s

Therefore the speed that the astronaut move toward the capsule is 1.09m/s

Answer:

Explanation:

Given that,

Mass of astronaut

M = 62kg

Mass of wrench

m = 3.3kg

Speed at which wrench move away from the capsule

v = 20.5m/s

Speed of astronaut?

Let speed of astronaut be V

Since there is no external force, we would apply conservation of momentum

Momentum of the astronaut is equal to the momentum of the wrench

Momentum is given as

P = Mass × Velocity

P(astronaut) = P(wrench)

M×V = m×v

V = m×v/M

V = 3.3×20.5/62

V = 1.09 m/s

The astronaut speed is 1.09m/s

Answer:

Direction is N 51.3° E

Explanation:

» From trigonometric ratios:

{ \tt{ \red{ \tan( \theta) =  \frac{opposite \: { \blue{(south)}}}{adjacent \: { \blue{(west)}}}  }}} \\  \\ { \tt{ \tan( \theta)  =  \frac{50}{40} =  \frac{5}{4}  }} \\  \\ { \tt{ \theta =  { \tan }^{ - 1} ( \frac{5}{4}) }} \\  \\ { \tt{ \theta = 51.3 \degree}} \\  \\ { \boxed{ \tt{ \: direction : \:{ \green{N }}\: 51.3 \degree \: { \green{ E }}}}}

How is Uranus colder than Neptune
STatiana [176]
With Uranus at an average distance of 2.88 billion kilometres from the Sun and Neptune at an average distance of 4.5 billion kilometres it would be very easy to point out which of the gas giants is the coldest, but if you were you were to say that Neptune was the coldest, you’d be wrong.<span>Given that we expect planets further from the Sun to be colder than those closer, this does make Neptune and Uranus quite a mysterious pair. Uranus and Neptune are brimming with volatiles such as water, methane and ammonia and due to their composition in comparison to Jupiter and Saturn, which are comprised mainly of hydrogen and helium, are labelled the ice giants. Scientists have measured how hot Uranus and Neptune should be and have found that Uranus is very cold and very dim</span>

If two oscillators connected to speakers create frequencies of 594 hz and 600 hz, what is the beat frequency when you hear both
Annette [7]
When we have two sound waves with frequencies f1 and f2 that interfere, the beat frequency is equal to the absolute value of the difference of the two frequencies, so in our problem:
f_{beat}=f_2-f_1 = 600 Hz-594 Hz = 6Hz
