Answer:
Explanation:
Let m be the mass of a little car and m' be the mass of another car.
We know that,
Force = mass × acceleration
ATQ,
m × a = 2m × a'
a = 2 × a'
So, the acceleration of another little car is equal to .
Answer:
5 m/s 2
To
get the acceleration of a car, you need to know first the difference in the
change in speed of a car then divided by time of the change. This can be
expressed as acceleration =
(change in speed) divided by (time for the change). So 30 m/s minus 10 m/s is
equal to 20 m/s divided by 4 seconds and the quotient is 5 m/s2.

This is something for biology, it shouldnt be in the physics subject
Explanation:
Answer:
Transduction.
Explanation:
Transduction is actually a process which involves the conversion of energies or messages from one kind to another. So in this case the transfer of light energy received by the eyes into the message for the brain is also called as transduction.
Answer:
a) 2.02 years
b) 8.1 x 10⁻⁸.
Explanation:
Time period of a rotating body T² is proportional to radius of orbit R³ So
T₁² / T₂² = R₁³ /R₂³ ( T₁ and R₁ is time period and radius of orbit of the earth .)
1² / T₂² =( 1/1.6)³
T₂ = 2.02 years.
Kinetic energy of an orbiting body = 1/2 m v₀² ( v₀ is orbital speed)
= 1/2 m x 2 g R = m x G m/R² X R= m² x G /R
Kinetic energy of asteroid K₁ / kinetic energy of earth K₂ =
(mass of asteroid/mass of earth)² x( radius of earth / radius of asteroid)
=( 3.6 x 10⁻⁴)² x 1/1.6 = 8.1 x 10⁻⁸ .
