Answer:
Science seeks to broaden our knowledge base, while engineering designs solutions and problems.
Explanation:
Answer:
A vector quantity is a quantity that has both magnitude and direction.
Explanation:
Distance = speed x time. The total speed is 30 + 60 = 90km/h and the total time taken is 15 + 15 = 30 minutes. Therefore, you do 90 x 30 = 2700km
Answer = 2700km
Answer:
(c) The wall exerts a greater force on the 2 kg ball than on the 5 kg ball since the force from the wall on each ball is equal to the force that each ball exerts on the wall.
Explanation:
According to Newton's third law of motion,"action and reaction are equal and opposite".
If a 2 kg ball exerts a force of 10,000 N on a wall, the wall will also exert a force of 10,000 N on the 2 kg ball but in opposite direction.
Similarly, If a 5 kg ball exerts a force of 5,000 N on a wall, the wall will also exert a force of 5,000 N on the 5 kg ball but in opposite direction.
Regardless of mass of the ball, the wall will exert equal force with which the ball collide with it.
Therefore, the wall exerts a greater force on the 2 kg ball than on the 5 kg ball since the force from the wall on each ball is equal to the force that each ball exerts on the wall.
