Physics
1 answer:
bogdanovich [222]3 years ago

Answer:

Distance = 25000000 miles

Time = 50 hours

Explanation:

Venus is the closest planet to Earth. It is about 25 million miles away from Earth. Its precise distance depends on where both Venus and Earth are in their respective orbits

Given that

Speed V = 500000 mph

Distance d = 25 000,000 miles

Speed = distance/ time

Time = distance/speed

Time = 25000000/500000

Time = 50 hours

It will therefore take 50 hours to get to venus at that speed.

Hamish is studying what happens when he sends a sound
horrorfan [7]

Wave 3 will move the slowest, the statement could made about the data collected in Hamish's table

Answer: Option C

<u>Explanation: </u>

Sound waves require medium to pass from one to another. Depending upon the density of molecules in the medium, the speed of the sound waves can be determined. As we know that compression and rarefactions will be formed for propagation of sound waves when the waves collide with molecules of the medium.

So, if there is less molecules present in the medium or loosely packed molecules present in the medium with high mean free path length than the sound wave will be travelling slowly in that medium.

Thus, as we known that gas has the loosely packed molecules among the other states of matter, so wave 3 which is made to pass through the gas medium will be propagation at the lowest speed or will move the slowest compared to other 3 gases made to propagate in solid and liquid mediums.

Question 6 (14 points)
leva [86]

Answer:

a=114\ m/s^2

Explanation:

Given that,

Mass of an object, m = 3.68 kg

It is whirled in a horizontal circle of radius 881 cm or 8.81 m

The object completes 10.8 revolutions every 18.8 s.

We need to find the centripetal acceleration of the object. It is given by the formula as follows :

a=\omega^2 r ...(1)

Where \omega is angular velocity

10.8 revolutions = 67.85 rad

\omega=\dfrac{67.85\ rad}{18.8\ s}\\\\=3.6\ rad/s

Put values in equation (1)

a=3.6^2\times 8.81\\\\a=114\ m/s^2

So, the centripetal acceleration of the object is 114\ m/s^2.

If you do 200 joules of work using a force of 50 newtons, over what distance was the force applied ?
harina [27]
By using the formula for work, we can derive the force

W = Fd
F= \frac{W}{d} = \frac{200}{50} = 4 N

If you found that helpful, please rate this as "Brainiest"

A sign is hung between two cables. If the sign weighs 350 N, what is the tension (in N) in each cable?
Gre4nikov [31]

Answer:

Tension in each cable = 175 N

Explanation:

Given:

Number of cables = 2

Weight of sign board(T) = 350 N

Find:

Tension in each cable

Computation:

We know that,

T1 = T2

So,

T1 + T2 = T

T1 + T2 = 350

T1 + T1 = 350

T1 = 175

Tension in each cable = 175 N
