With that information, you can determine the object's speed.
Just divide the distance covered by the time to cover the distance.
If you also know the direction the object moved, then you can
determine its velocity. If you don't, then you can't.
We know the equation
weight = mass × gravity
To work out the weight on the moon, we will need its mass, and the gravitational field strength of the moon.
Remember that your weight can change, but mass stays constant.
So using the information given about the earth weight, we can find the mass by substituting 100N for weight, and we know the gravity on earth is 10Nm*2 (Use the gravitational field strength provided by your school, I am assuming yours in 10Nm*2)
Therefore,
100N = mass × 10
mass= 100N/10
mass= 10 kg
Now, all we need are the moon's gravitational field strength and to apply this to the equation
weight = 10kg × (gravity on moon)
Answer:
I THINK option A is correct
Explanation:
because the electrostatic force is directly proportional to product of charges
now if the force between two electron is F charge on electron is same so their product is positive now the charge on proton is +ve and on electron is -ve so their product is -F
Hello!!
For calculate the velocity let's applicate the formula:
d = Distance = 4000 m
v = Velocity = ?
t = Time = 400 s
⇒ 
⇒ 
I think it’s 15cm
Might be 7cm
