Recall that
where 
and 
are the initial and final velocities, respecitvely; 
is the acceleration; and 
is the change in position.
So we have
(Normally, this equation has two solutions, but we omit the negative one because the car is moving in one direction.)
Answer:
B
Explanation:

Answer:
Explanation:
Relation between energy and momentum is as follows .
E = h c / λ
E / c = h / λ
h /λ = momentum of a photon
momentum of a photon = E /c
= 11 x 10³ / 3 x 10⁸
= 3.67 x 10⁻⁵
In 4 days no of photon
= 4 x 24 x 60 x 60 = 345600 .
momentum of photon released
3.67 x 10⁻⁵ x 345600 .
= 12.68 kg m/s
This momentum will be imparted to spaceship .
12.68 = mv
12 .68 = 1300 x v
v = .00975 m /s
= 9.75 mm /s
We know, For a substance they both are equal in magnitude, i.e.,
Specific Gravity = Density
Specific Gravity = 19.3 [ As Density = 19.3 ]
In short, option C would be your correct Answer!
Hope this helps!
Answer:
A) Inertia
Explanation:
Inertia is why objects tend to resist changes in their motion. Like a rolling ball will keep rolling unless we try to add friction to it, which then would stop the ball.
