Answer:
The velocity of the ship relative to the earth V = 9.05
Explanation:
The local ocean current is = 1.52 m/s
Direction = 40°
Velocity component in X - direction = 1.52 °
= 1.164
Velocity component in Y - direction = 8 + 1.52 °
= 8.97
The velocity of the ship relative to the earth
Put the values of and we get,
⇒
⇒ V = 9.05
This is the velocity of the ship relative to the earth.
Answer:
A maximum
Explanation:
When displacement is maximum, velocity is Zero and vice versa
When displacement is maximum, acceleration is maximum and when it is zero, acc. Is zero
(a). If the temperature of a substance is increased the density of it will also increased. The temperature is directly proportional to the density because the molecular activity of the substance will be affected by the temperature
(b).The mass of the substance doesn't at all. Because the amount of matter inside the substance cannot be affected by the temperature except that its water
The seat belt is applying a force in the opposite direction.
