Answer:
PLEASE MARK ME BRAINLIEST!!!
Explanation:
Given initial velocity of ambulance
v0=18m/s , acceleration a=5m/s2
To find distance, x=?
First we need to calculate the time for which it acquires 30\,m/s. For that use equation
v=v0+at
30=18+5×t
⇒t=30−185=125seconds
Distance travelled by the ambulance
x=v0t+12at2
x=(18×125)+12×5×(125)2
x=43.2+2.5×5.76=43.2+14.4
x=57.6m
Therefore the ambulance has to travel 57.6 m to match the velocity of car.
A ) <em>Speed</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>scalar quantity and velocity is a vector quantity.</em>
The human beings use 10 % of the brain and the remaining 90 percent is full of unused potential and undiscovered abilities.
Explanation:
It is stated that every human beings use 10 percent of their brain and the other 90 percent is used only for operating a limited stretch. the average adult human brain can store the 2.5 million gigabytes digital memory.
The human brains contains about 100 billion neurons and around i quadrillion to 1 million connections in the cells. The dendrites provide more information than passive wiring.
The unused part of the brain is not necessary it simply occupies the space. The damaged parts of the brain should be removed.
