An alternating current with a frequency of 100HZ has a period of
0.03sec
0.01sec
0.04sec
0.15sec
Correct answer is B
F = 100HZ, period, T = 1/f = 1/100
= 0.01 sec
The period (T) = 0.01sec
Momentum and Kinetic energy are conserved in
Inelastic collision
Elastic collision
Explosion
Spacecraft
Correct answer is B
Momentum and kinetic energy are conversed in elastic collision
The property of a body to remain at rest or to continue to move in a straight line is known as
force
Impulse
Energy
Inertia
Correct answer is D
Inertia: the property of a body that resists any change to its uniform motion, equivalent to its mass
The normal temperature of human body is record at what ranges?
27°C to 43°C
30°C to 40°
98.4°C only
Between 35°C to 37°C
Correct answer is D
The range of temperature is between 35°C and 43°C but for normal temperature of human body is between the range of 35°C to 37°C respectively
I only
II and IV only
II only
III only
Correct answer is B
In an inelastic collision, linear momentum is conserved and energy is decreased
Momentum and kinetic energy are conserved in elastic collision
