How much force would is required to stop a 1200kg car in 2 seconds if the car is traveling at 22 m/s
Shalnov [3]
Force required = F = ?

mass of the car = m = 1200 kg

initial velocity of the car = Vi = 10 m/sec

final velocity of the car = 0

time required to stop the car = t = 20 sec

Using Newton`s 2nd law of motion;

F = ma ………………………(1)

as a = Vf - Vi / t , put this value in equation (1)

F = m ( Vf - Vi /t ) ………………(2)

F = 1200 ( 0 - 10 /20) = - 600 N

here Negative sign shows that external force is acting in opposite direction of the motion to bring it to rest.

we can also calculate this force by using the relation

Rate of change of momentum = net force acting on the object …………(3)

m Vf - m Vi / t = net force acting on the object

m (Vf - Vi / t) = F

1200 ( 0 - 10 /20) = - 600 N = F

so, net force acting on the object =F = - 600 N

Explain how abiotic factors and biotic factors affect population growth.
Semmy [17]

The carrying capacity is impacted by both biotic and abiotic processes. The carrying capacity develops as these conditions improve. The carrying capacity decreases as the factors grow scarcer. When resources are depleted faster than they are replaced, the species has reached its carrying capacity.

<h3>What is carrying capacity?</h3>

The average population size of a species in a given habitat is referred to as carrying capacity.

Environmental considerations such as appropriate food, shelter, water, and mates limit the species population size.

The carrying capacity is impacted by both biotic and abiotic processes. The carrying capacity develops as these conditions improve.

The carrying capacity decreases as the factors grow scarcer. When resources are depleted faster than they are replaced, the species has reached its carrying capacity.

Thus, in this way abiotic factors and biotic factors affect population growth.

Choose all the true statements about oxidative phosphorylation.
irga5000 [103]

Answer:

A. Oxidative phosphorylation occurs in the inner mitochondrial membrane.

B. The oxidation of NADH provides enough energy to produce three ATP molecules.

Explanation:

Oxidative phosphorylation is the third step of cellular respiration, in which NADH2 or FADH electron carriers are oxidized to produce ATP. Oxidative phosphorylation occurs in the inner mitochondrial membrane. It is composed of two processes viz: electron transport chain and chemiosmosis.

Either NADH2 or FADH is used as the starting electron carrier. When NADH is used, its oxidation produces enough energy to generate 3 molecules of ATP per molecule while FADH generates 2 ATP molecules.
