Using what you know about newton's second law explain why a car with a lager mass use more fuel than a car with a smalle mass. a

NNADVOKAT [17]

The car with bigger Mass requires more fuel because More mass the heavier it gets. you can't grab the little car fuel tank and put it in the big car it will run out to fast.

overall answer : The bigger the mass = more weight which means it needs more fuel to run

A sports car traveling along a straight line increases its speed from 19.8 mi/h to 59.9 mi/h.a. What is the ratio of the final t

Natasha2012 [34]

Answer

given,

initial speed of the car (v₁)= 19.8 mi/h

final speed of the car (v₂)= 59.9 mi/h

a) initial momentum = m v₁

P₁ = 19.8 m

final final momentum = m v₂

P₂ = 59.9 m

ratio = $\dfrac{P_2}{P_1}$

= $\dfrac{59.9 m}{19.8 m}$

ratio of momentum= $\dfrac{P_2}{P_1}=3.025$

b) initial kinetic energy= 1/2 m v₁²

K₁ = 196.02 m

final kinetic energy= 1/2 m v₂²

K₂ = 1794.005 m

ratio = $\dfrac{K_2}{K_1}$

= $\dfrac{1794.005 m}{196.02 m}$

ratio of Kinetic energy= $\dfrac{P_2}{P_1}=9.15$

An ideal spring has spring constant ks (to distinguish it from the electrostatic constant k) and equilibrium length l. Then, you

nexus9112 [7]

Answer:

q = square root (4KsL³/k)

The force of extension of the spring is equal to the force of repulsion between the two like charges. Two like charges(positive or negative) would always repel each other and two unlike charges would always attract each other. This electric force between the charges is what is responsible for the stretching of the spring. The electric force causes the spring to increase in length from L to 2L. Equating these forces, that is the electric force between the charges and the elastic force of the spring and rearranging the variables gives the expression to obtain q.

See the attachment below for full solution.
