what would you say is the strongest force in our galaxy? the sun, moon, or earth. support the answer with at least two facts.
Lilit [14]
I think sun because:
-Sun is the strongest force. It has the largest gravitational pull.
-the moon and Earth both depend on the Sun for different things.
-The sun is not greatly affected by the Moo or the Earth.

395,000 meters in 9000
marta [7]

Answer:

43.88 meters per second

Explanation:

The computation of the speed is shown below:

As we know that

Speed = \frac{Distance}{time}

where,

Distance is 395,000 meters

Time is 9,000 seconds

Now placing these values to the formula

So, the speed is

= \frac{395,000}{9,000}

= 43.88 meters per second

As speed shows the relation between the distance and time and the same is to be considered i.e by applying the formula

This physics problem is kinda complicated to my small brains...
Veronika [31]

Answer:

\huge\boxed{\sf P.E. = 14700\ Joules}

Explanation:

This work done is in the form of Potential Energy so we'll use the formula of Potential Energy.

<u>Given Data:</u>

Mass = m = 250 kg

Acceleration due to gravity = g = 9.8 m/s²

Height = h = 6 m

<u>Required:</u>

Work Done in the form of Potential Energy = P.E. = ?

<u>Formula:</u>

P.E. = mgh

<u>Solution:</u>

P.E. = (250)(9.8)(6)

P.E. = 14700 Joules

\rule[225]{225}{2}

Hope this helped!
