<u>We are given:</u>
Mass of the rocket = 10 kg
Weight of the Rocket = 100 N
Upward thrust applied by the rocket = 400 N
<u>Net upward force on the rocket:</u>
We are given that gravity pulls the rocket with a force of 100 N
Also, the rocket applied a force of 400N against gravity
Net upward force = Upward thrust - Force applied by gravity
Net upward force = 400 - 100
Net upward force = 300 N
<u>Upward Acceleration of the Rocket:</u>
From newton's second law:
F = ma
<em>replacing the variables</em>
300 = 10 * a
a = 30 m/s²
Answer:
attracting iron and producing a magnetic field
Almonds, like many nuts, are one of the best plant sources of protein. Protein will help regulate your blood sugar and keep your energy level stable throughout the day. Oats contain the energizing and stress-lowering B vitamin family, which helps transform carbs into usable energy. Water, without water, your body cannot generate energy.
