The acceleration due to gravity on Jupiter is 24.79 m/s²,
compared to 9.8 m/s² on Earth ... a ratio of about 2.53 .
So if a person or object were somehow transported to Jupiter,
he/it would weigh
(2.53) times (Earth weight)
there.

Answer:
F = -49.1 10³ N
Explanation:
Let's use the kinematics to find the acceleration the acceleration of the bullet that they tell us is constant
² = v₀² + 2 a x
Since the bullet is at rest, the final speed is zero
x = 11.00 cm (1 m / 100 cm) = 0.110 m
0 = v₀² + 2 a x
a = -v₀² / 2 x
a = -1320²/(2 0.110)
a = -7.92 10⁶ m / s²
With Newton's second law we find the force
F = m a
F = 6.20 10⁻³ (-7.92 10⁶)
F = -49.1 10³ N
The sign means that it is the force that the tree exerts to stop the bullet
Answer:
Explanation:
At room temperature the thickness of the film is just enough that it will cancel the reflected light
So here we will have
so we have
here we have
now we have
now when temperature is increased to 177 degree C
then in this case we have
now we have
now we know by the formula of thermal expansion
