Answer:

Work done W 2.938*10^9 J

Explanation:

given data:

mass m = 944 Kg

Mass of moon M = 7*10^22 Kg

Radius of the moon R = 1.5*10^6 m

gravitational constant G = 6.67*10^{-11} Nm^2/Kg^2

we know that work done is given as

Work done W = \frac{GMm}{R}

                      = \frac{6.67*10^{-11}*7*10^{22}*944}{1.5*10^6 m}

                      = 2.938*10^9 J

An archer shot a 0.06 kg arrow at a target. The arrow accelerated at 5,000 m/s2 to reach a speed of 50.0 m/s as it left the bow.
laila [671]

Answer:

300 N

Explanation:

The net force acting on the arrow is given by Newton's Second Law:

F=ma

where

m = 0.06 kg is the mass of the arrow

a = 5,000 m/s^2 is the acceleration of the arrow

Substituting the numbers into the equation, we find

F=(0.06 kg)(5,000 m/s^2)=300 N

Imagine that you set your watch at local noon in Kansas City on Monday and then fly to the Coast on Tuesday. You stick a pole in
Sergeu [11.5K]

Answer: East Coast

Explanation:

The problem states we need to find whether the person is on the East Coast or West Coast.

Now, we know that the shadow is shortest when the Sun is at the highest point in the sky. So it means the noon time is 12:00 P.M. Now this is the local noon time which you have set in Kansas City. Now you flew to the Coast and it says 10:00 am which means you have traveled to a place where noon comes early. And noon comes early on Eastern Coast so you are on the East Coast.

A star's apparent magnitude is most closely related to which of the following? Select all that apply.
kramer
If you want the "most", then you can't have more than one.

A star's apparent magnitude is determined by both its intrinsic luminosity
and its distance from us.

A student said, "The displacement between my dorm and the lecture hall is 1 kilometer."
Ann [662]

Answer:

d) Both a and b are correct

Explanation:

Displacement: It is defined as the distance between initial and final position during motion.

Distance: It is defined as the total path length traveled by object

Or

It is the distance of one place from other place.

Student said that the displacement between my dorm and the lecture hall is 1km.

It is not displacement .It is distance or we say path length.

Therefore, he is using  incorrect physical quantity for the information provided.

He should have called distance 1 km or path length 1 km.

Option d is true.
