A more realistic car would cause the wheels to spin in a manner that would result in the ground pushing it forward with a consta

nt force (in contrast to the constant power in Part A). If such a sports car went from zero to 31.0 in time 1.40 , how long would it take to go from zero to 62.0 ?

Answer:

acceleration = 22.14 m/s²

time = 2.80 s

Explanation:

given data

initial velocity = 31.0

final velocity =

time = 1.40

solution

we get here acceleration that is

acceleration = \frac{v(final) - v(initial)}{t}   ...............1

acceleration = \frac{31-0}{1.40}  

acceleration = 22.14 m/s²

and

by kinematic equation of motion

v = u +at .........2

t = \frac{62-0}{22.14}  

time = 2.80 s

san4es73 [151]

Answer:

1. enhance learning and memory ability in nonhuman organisms.

Explanation:

Genetic engineering can be defined as the process by which scientists modify the genome of an organism using new molecular tools. The resulting organism after the modification is known as Genetically Modified Organisms (GMO).

To create this genetically modified organisms requires recombinant DNA.

Advances in genetic engineering show that it is possible to enhance learning and memory ability in nonhuman organisms through biotechnology.

The energy transformations that occur as you coast down long hill on a bicycle, including the brakes to make the bike stop at the bottom, is that at the top of the hill you have high GPE AND LOW KE, on your way down you have HIGH KE AND LOW GPE, and at the bottom you have thermal energy due to the stop of the brakes.

the law of conversation of energy and describe the energy transformations that occur as you coast down a long hill on a bicycle and then apply the brakes to make the bike stop at the bottom.

Two balls have the same mass of 5.00 kg. Suppose that these two balls are attached to a rigid massless rod of length 2L, where L
olga_2 [115]

Answer:

Explanation:

Given

mass of balls m= 5 kg

N=45.6 rev/s

angular velocity \omega =2\pi N=286.55 rad/s

Length of Rod 2L=1.1 m

Tension in the Second half of rod

T_2=m\omega ^2(2L)=2m\omega ^2L

T_2=5\times (286.55)^2\times 1.1

T_2=451.609 kN

For First Part

T_1-T_2=m\omega ^2L

T_1=T_2+m\omega ^2L

T_1=3 m\omega ^2L

T_1=3\times 5\times (286.55)^2\times 0.55

T_1=677.41 kN

The equation shows neutralization of an acid and a base to produce a salt and water.
Masja [62]

The answer is; 2.

To balance a chemical equation, the moles on one side of the equation has to be the same as that on the other side. This ensures that the law of conservation  is observed because matter or energy can't be created or destroyed but can only be transformed from one form to another.

In this equation, putting 2 in front of NaCl ensures that there are 2 moles of Na and CL just as there are 2 moles of Na and CL in the reactants side.
