An object's velocity can be described by its speed and acceleration.
This statement is true
Hope this helps
Have a great day (:

Answer:

Explanation:
Here by ideal gas equation we can say

now we know that pressure is kept constant here
so we will have

since we know that number of moles and pressure is constant here
so we have

now we know that initial temperature is 17.8 degree C
and finally volume is doubled
So we have

so final temperature will be


2. Groups
3.Ion
4.NonPolar
5.Metallic Bond
6.Make up most of the atom's mass
7.Atomic Number
8.Seven
To solve this problem we will use the definition of the kinematic equations of centrifugal motion, using the constants of the gravitational acceleration of the moon and the radius of this star.
Centrifugal acceleration is determined by

Where,
v = Velocity
r = Radius
From the given data of the moon we know that gravity there is equivalent to

While the radius of the moon is given by

If we rearrange the function to find the speed we will have to



The speed for this to happen is 1.7km/s
