Answer:
speed in km/min:
0.3km/min
speed in km/h:
18km/h
speed in m/s:
5m/s
Explanation:
the average speed is defined as:
where 
is the speed, 
is the distance traveled, and 
is the time
according to the statement:
and
(10 minutes are equal to a sixth of an hour which is 600 seconds)
Because the units in which the speed is required are not indicated, here are some options for the answer:
Depending on the units in which you need the speed, are the quantities you should use.
Speed in km / h (kilometers per hour):
speed in m / s (meters per second):
or the speed in km/min (kilometers per minute)
Speed depends on time and distance.
Answer:
temperature
Explanation:
In general, the specific heat also depends on the temperature. The table below lists representative values of specific heat for various substances. Except for gases, the temperature and volume dependence of the specific heat of most substances is weak.
Answer:
(for small oscillations)
Explanation:
The total energy of the pendulum is equal to:
For small oscillations, the equation can be re-arranged into the following form:
Where:
, measured in radians.
If the amplitude of pendulum oscillations is increase by a factor of 4, the angle of oscillation is 
and the total energy of the pendulum is:
The factor of change is:
Given :
Initial velocity, u = 12.5 m/s.
Height of camera, h = 64.3 m.
Acceleration due to gravity, g = 9.8 m/s².
To Find :
How long does it take the camera to reach the ground.
Solution :
By equation of motion :
Putting all given values, we get :
t = 2.56 and t = −5.116.
Since, time cannot be negative.
t = 2.56 s.
Therefore, time taken is 2.56 s.
Hence, this is the required solution.
