Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In re-action, a thrusting force is produced on the engine mount. The thrust accelerates the rocket as described by Newton's second law of motion.
Explanation:
Answer:
The distance is 19.58 m.
Explanation:
Given that,
Mass = 3.0 kg
Radius = 1.3 m
Angular speed = 6.8 rad/s
Angle = 24°
Acceleration of gravity = 9.81 m/s²
We need to calculate the distance
Using formula of kinetic energy
Total Initial kinetic energy,
....(I)
Now, Total potential energy
....(II)
Equating equation (I) and (II)
Hence, The distance is 19.58 m.
Answer:
The final temperature is 85.86°C.
Explanation:
Given that,
Mass of tea = 200 g
Mass of glass = 150 g
Initial temperature = 25°C
We need to calculate the final temperature
When equilibrium is reached, assuming no heat flows to the surroundings
So,
We know that,
Specific heat of tea = 1.00 cal/gm° C
Specific heat of tea = 0.20 cal/gm° C
Put the value into the formula
Put the value of initial temperature
Hence, The final temperature is 85.86°C.
