Answer: After one hour the distance will be 64 800 meters, after 1 minutes the distance will be 1080m, after 1 sec the distance will be 18m.
Explanation: Distance is speed multiplied by the time taken.
Using the standard formula V= d/t
Where v is a velocity,
D is a distance and
t is time.
We get use the formula to multiply the time taken by the velocity.
Answer:
Parameter is population mean = 65 c
Explanation:
There are two important aspects in the study of samples and inferring the behaviour of population.
TO know the mean of the population, normally we draw different samples and find their mean. The mean of all means will be an estimate for the populatio mean. By central limit theorem, mean of a sample tends to be normal as sample sizes grow with estimated mean as mean of sample.
While a statistic describes a sample, a parameter describes an entire population.
Here 65 degrees C is for entire population hence this is a parameter.
No. Speed is speed and force is force.
Answer:
Angle of refraction.
Explanation:
Refraction is simply a change in direction of light rays as it enters into another medium.
In the diagram given above, θ2 is simply the angle of refraction showing us that the light ray has changed direction as it moves from one medium to another medium.
Answer:
a. wedge
Explanation:
The wedge machine is used to separate, lift or split
objects. It is triangular in shape with a tapered formation thick and blunt on one end, thin on the other end (the edge)
