Explanation:
Newton's second law of motion states that when a certain force is acted on an object then it is equal to the mass m of that object multiplied by the acceleration a of the object.
Mathematically, the relation is as follows.
F = m × a
Thus, we can conclude that when an object is acted on by an unbalanced force then the object will start to accelerate.
Answer:
(a) 200.0628 N ; ( b) 4.08Kg
Explanation:
We know,
w = mg [here w= weight , m= mass , g= gravity]
now,
gravity on earth (g) =9.807 m/s²
mass of the spanner (m)=?
weight of the spanner on earth(w) = 40N
⇒ w = 40N
⇒m g =40N
⇒m = (40/g) Kg
⇒m= (40/9.807)Kg
∴m=4.08Kg
∴mass of the spanner on earth = 4.08Kg
We know,
Mass is the amount of matter in an object . Somass will remain same both on earth and jupiter.
So,
(b)The mass of the spanner on jupiter = 4.08Kg
Now,
The mass of the spanner on jupitar (m) = 4.08Kg
Gravity on jupiter (g*) = 5.g [5 times on earth]
= 5 . (9.807)m/s²
=49.035 m/s²
(a)
∴weight of the spanner on jupitar(w*) = m g*
=(4.08 x 49.035) N
=200.0628 N
sliding friction
rolling friction
drag
Answer:
Drag friction.
Explanation:
If you have a solid object, go through air, it experiences drag because the air molecules push back a tiny bit. This drag is enhanced because in water, the molecules are more resistant than air, that's why if you try to run in knee deep water, you experience much more drag than when you are running with your legs out of the water.
A wave with a large amplitude has a lot of a.vibration b.speed c.energy
Answer:
A high amplitude wave carries a large amount of energy; a low amplitude wave carries a small amount of energy. The average amount of energy passing through a unit area per unit of time in a specified direction is called the intensity of the wave.
