Answer:
The distance travelled does not depend on the mass of the vehicle. Therefore, 
Explanation:
This deceleration situation can be analyzed by means of Work-Energy Theorem, where change in translational kinetic energy is equal to the work done by friction:
(1)
Where:
- Mass of the car, in kilogram.
- Initial velocity, in meters per second.
- Coefficient of friction, no unit.
- Travelled distance, in meters.
Then we derive an expression for the distance travelled by the vehicle:
As we notice, the distance travelled does not depend on the mass of the vehicle. Therefore,
you could make a self propelled car all you need is cardboard, wheels, and a balloons or rubber bands
Answer:
Yes, Centripetal Force acts on the Car.
Explanation:
When a car undergoes a circular motion, a centripetal force acts onto it.
Centripetal Force = [m*(v^2)]/R , where
- R is the radius of curve
- v is the constant speed
- m is the mass of the car
Answer:
12 km/h
Explanation:
Let v represent Yashvi's speed in km/h.
time = distance/speed
48/v -1 = 48/(v+4) . . . . time is 1 hour less at v+4 km/h
48(v+4) -(v)(v+4) = 48v . . . . . multiply by v(v+4)
48v +192 -v^2 -4v = 48v . . . eliminate parentheses
v^2 +4v -192 = 0 . . . . . . . . . . put in standard form
(v -12)(v +16) = 0 . . . . . . . . . . factor
v = 12
Yashvi's speed is 12 km/hour.

<em>Check</em>
At 12 kph, it takes 48/12 = 4 hours to ride 48 km. At 12+4 = 16 kph, it takes 48/16 = 3 hours to ride 48 km. That's 1 hour less, as it should be
Answer:
Volume will increase by factor 2
So option (A) will be correct answer
Explanation:
Let initially the volume is V pressure is P and temperature is T
According to ideal gas equation 
, here n is number of moles and R is gas constant
So 
....................eqn 1
Now pressure is doubled and temperature is quadrupled
So new volume 
........eqn 2
Now comparing eqn 1 nad eqn 2
So volume will increase by factor 2
So option (A) will be correct answer
