Answer:
A) true
33) Osha data : true
34 ) False
Explanation:
A) Karl Landsteiner was the first to classify blood on the basis of modern theory .
33) OSHA ( Occupational Safety and Health Administration ) data relates to the safety measures that are taken by a unit or firm to avoid hazardous situation for their workforce.
34 ) There are as many as 150 points in an average finger prints that can be compared. Some country like England requires 16 point identification , some like France requires 17 points identification. So The statement is wrong.

Answer: 4850N
Explanation:
Mass of car = 970 kg
Time = 5 s
Speed = 25 m/s
Average force exerted on the car = ?
Recall that Force is the product of the mass of an object and the acceleration by which it moves
i.e Force = mass x acceleration
(Since, acceleration is the rate of change of velocity or speed per unit time)
i.e Acceleration = Speed / Time
Acc = 25m/s / 5s
Acc = 5m/s^2
Average force = mass x acceleration
Avg force = 970 kg x 5m/s^2
= 4850N
Thus, the average force exerted on the car is 4850 Newton
Answer:4s^-1
Explanation:Tangential Acceleration=v^2/r=(20)²/100=400/100
Answer:
Explanation:
NEWTON'S FIRST LAW OF MOTION:
a body continues its state of rest or of uniform motion in a straight line provided no net force acts on it. Fnet=0
NEWTON'S SECOND LAW OF MOTION:
when a net force acts on a body it produces acceleration in the body which is directly proportional to the magnitude of the net force and inversely to the mass of the body.F=ma
NEWTON'S THIRD LAW OF MOTION:
to every action there is always an equal but opposite reaction.
