Answer:

Basic units=those units of measurement which do not depend upon any other units are called basic units. Example length, mass, time, current etc. 

Derived units=those units which are expressed in terms of fundamental units are called derived units. Example area, volume, density etc.

A motorcyclist travels with an average speed of 6 m/s . If the cyclist is going to a friend's house 36 m away , how much time wi

vodka [1.7K]

Answer:

Explanation:

The time taken by the cyclist can be found by using the formula

$t = \frac{d}{v} \\$

v is the velocity

d is the distance

From the question we have

$t = \frac{36}{6} \\ = 6$

We have the final answer as

Hope this helps you

Aunt Matilda goes to a well and throws a penny straight down the well at 3.0 m/s. She hears a splash after 0.5 seconds. How deep

Answer : The correct option is (d) 2.73 m

Explanation :

By the 2nd equation of motion,

$s=ut+\frac{1}{2}at^2$

where,

s = distance or height = ?

u = initial velocity = 3.0 m/s

t = time = 0.5 s

a = acceleration due to gravity = $9.8m/s^2$

Now put all the given values in the above equation, we get:

$s=(3.0m/s)\times (0.5s)+\frac{1}{2}\times (9.8m/s^2)\times (0.5s)^2$

$s=2.73m$

Therefore, the correct option is (d) 2.73 m
