Answer: <u><em>Uranus is the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees – possibly the result of a collision with an Earth-sized object long ago. This unique tilt causes the most extreme seasons in the solar system. </em></u>
<u><em>Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue. Uranus also has faint rings. </em></u>
<u><em>The inner rings are narrow and dark.Like the other gas giants, Uranus has an atmosphere composed of mostly hydrogen, followed by helium and a little methane. What is very interesting about Uranus is that the planet has an enormous 98 degree tilt on its axis.</em></u>

Answer:
<h2>20 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 10 × 2
We have the final answer as
<h3>20 N</h3>
Hope this helps you
Answer:
T - M g - Ff = M a describes the acceleration of the object
T = M g + Ff if the object moves at constant speed (a = zero)
Ff = μ M g = .3 * 40 * 9.8 = 118 N the force of friction
Ff will be in a direction opposite to the motion
M g = 40 kg * 9.8 m/s = 392 N
a) T = M g + Ff for an object moving upwards
T = 392 + 118 = 510 N
b) T = M g - Ff for an object moving downwards
T = 392 - 118 = 274 N
Answer:
Explanation:
The expression for the second law of motion is given below:
h = 
<u>For first half distance</u>
Object is initially at rest, so its initial speed u = 0
Object falls at half the distance, so h = h/2 where t = t1
Hence, we have
<u>For second half distance:
</u>
Similarly,
where t = t1 + t2 and u= 0
Using equation 2 by equation 1
we obtain 
Hence 
Hence
