Answer:
a) 32.58 m/s²
b) 161.84 m/s
Explanation:
Initial velocity = u = 0
Final velocity = v = 145 m/s
Time taken = t = 4.45 s
s = Displacement of dragster = 402 m
a = Acceleration
The final velocity is greater than the velocity used to find the average acceleration due to the gear changes. The first gear in a dragster has the most amount of toque which means the acceleration will be maximum. The final gears have less torque which means the acceleration is lower here. The final gears have less acceleration but can spin faster which makes the dragster able to reach higher speeds but slowly.
Gravity
The moon doesn't smash into the earth because the gravity from the earth keeps the moon in orbit around it.
<span>Space.Energy can pass through the space only by radiation. In space there is no matter, liquids or solids to pass energy. The sunlight passes through space and reach earth and other planets in the form of radiation. Radiation is the transmission of energy in the form of electromagnetic waves which needs no medium.</span>
Answer:
A
Explanation:
hydrostatic pressure, P=hρg,
where 'h' is the ht of the liq column and ρ is the density of the liquid and 'g' is the effective acceleration, but as far as hydroSTATICS is concerned, g stands for the acceleration due to gravity
