Answer:
a) Option D
b) Option A
Explanation:
a) Option D
Because a massive car will have more inertia which will make the car move faster but a massive car simultaneously will have more friction thereby restricting its movement in the forward direction. Hence, all the three cars will move equal distance.
b) Option A, Car F
Being most massive car, the frictional force required to stop the car will be highest.
Answer:
"C" gravity increases with decreasing distance
Explanation:
A can be the answer too
Given that,
Acceleration, a = 9.71 m/s²
Force, F = 5050 N
mass, m = ?
Since, we know that
F=ma
m= F/a
m= 5050/9.71
m= 520.08 kg
The mass of hi car is 520.08 kilograms.
Answer:
Most psychiatrists and psychologists use the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) to diagnose mental health disorders.
