Acar has a mass of 1500 kg. if the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 7000 n.

if the car is moving at 18 m/s, what is the shortest distance in which the car can stop safely?

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
