We can push a bicycle easily, then a car because,  A) mass of the bicycle > mass of the car 

A) uniform motion

C) Larger the net force larger the acceleration

Correct option is A) 500 NS

The fundamental characteristic of the muscle is contraction. Therefore, muscle can only pull and not push the bone.

A) It produces greater pressure on the food.

A) first increases, then decreases

B) Streamlined shape

B) Liquids are not compressible

Correct option is (D) 3 Distance covered by car by travelling 60 kmph in 4 hours = speed \(\times\) time \(=60\times4\) = 240 km When car travels at 80 kmph then time by the car \(=\frac{Distance}{Speed}\) \(=\frac{240}{80}\) =...

Correct option is (D) 400 km Speed of the car \(=\frac{Speed}{Time}\) \(=\frac{300\,km}{6\,hours}\) = 50 km/h Distance travelled by the car in 8 hours = speed \(\times\) time = 50 km/h \(\times\) 8 hours = (50 \(\times\) 8) km = 400 km
