Answer:
The second step of the scientific method is the question being researched, the hypothesis. ... This hypothesis includes the explanation for the observation, it can be tested, and new conclusions may be reached. The third step of the scientific method is the experiment.
Explanation:
Mass of the car = 1200 kg
Mass of the truck = 2100 kg
Total mass of car and truck = 2100 + 1200 = 3300 kg
Since, the car pushes the truck. Hence, they will move together and will have same acceleration.
Let the acceleration be a.
According to Newton's second law:
F(net) = ma
F = 4500 N
4500 = 3300 × a
a = 1.36 m/s^2
Let the force applied by the car on truck be F.
F = F(net) on the truck
F = ma
F = 2100 × 1.36
F = 2856 N
Hence, the force applied by the car on the truck is 2856 N
Explanation: <u>Nurture</u> means to close or stop a living thing from multiplying (Giving birth). <u>Nature</u> is a place where animals and plants are found. Waterfalls are also found in nature.
<u>Genes is nature.</u>

Answer:
Velocity of Gulf Stream= west of north at a speed of
Explanation:
Given
- speed of ship relative to Gulf stream= west of north at a speed of 4 m/s
- speed of ship relative to earth= west of north at a speed of 4 .8 m/s
Let be the velocity of the ship relative to the earth and be the velocity of the ship with respect to the Gulf stream
Let the west direction be negative x axis and north direction be positive x axis
Now
magnitude of the velocity is given by
Let the velocity of gulf stream makes an angle with the positive y axis we have
Velocity of Gulf Stream west of north at a speed of
