Answer:
Inelastic
Explanation:
The price elasticity of demand is the degree of responsiveness of demand for a product or service to a unit change in price. The demand for a product is said to be elastic when a change in price has a relatively large effect on the demand for the product, unitary when there is a percentage change in price brings about an equal percentage change in the demand for the product, and inelastic when a change in the price of a product brings about a smaller change in the demand for the product.
In the case of the DVD rentals, a 10% increase in price brought about only a 5% drop in demand. Hence, the demand for DVD rentals is said to be inelastic because a change in the price brought about a smaller change in the demand for DVD rentals.

meters/seconds?
Answer:
0.25m/s
Explanation:
D = 450m
T = 1800s
S = 450÷1800

The average speed will be equal to 0.25 meters per second.
What is an average speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that 200 meters to school and another 250 meters to your friend's
house. This whole trip took 30 minutes.
The total distance is D = 450m
T = 1800s
The average speed will be calculated as
S = Total distance / Total time
S = 450÷1800

Why is it that a whole orange will float on water but a peeled one will sink
The peeled orange is much heavier than the water and hence it sinks and the whole orange is float as it is less denser than water.
The objects that float or sink depend on the buoyancy. Buoyancy is the tendency of the object to float in the liquids or fluids. When an object is immersed in a fluid, the object experience an upward force called buoyancy.
When the object sinks, its weight is less than the upward force or buoyancy. When the object floats, its weight is greater than the upward force.
The whole orange has a rind and the rind have tiny air pockets. When the orange is immersed in water, the water enters into the tiny air pockets and makes the orange less weight than the upward force and hence it floats.
When the rind is removed from the orange, the water can not enter the orange. Thus, the weight of the orange is greater than the upward force. Hence, it sinks.

how does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?
Answer:
F' = 9F
Explanation:
The electric force between charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
It means,
[tex]F\propto \dfrac{1}{r^2}[/tex]
If distance decreased by a factor of 3, r' = r/3
Net force will become,
[tex]F'=\dfrac{kq_1q_2}{r'^2}\\\\=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\=9\dfrac{kq_1q_2}{r^2}\\\\=9\times F[/tex]
It means new force will become 9 times that of the initial force.
Answer:

At t = 4.0 s, the elevator door opens and remains open for 5.0 s. The student immediately exerts a larger constant force on the box and the front of the box reaches the elevator door just as it start
to close.
() Calculate the magnitude of the new force that the student exerts.
Explanation:
Given,
mass of block = 30 kg
initial speed = 1.2 m/s
coefficient of friction = 0.20
time for elevator close and opening = 5.0 sec
for t= 0 sec to t= 4.0 sec
acceleration = 0
speed = 1.2 m/s
distance x= vt
at t=4 distance is x=4.8m
for t= 4.0 sec to next 5 second or t= 9.0 sec
the remaining distance for cover is
x= 16-4.8
x=11.2 m
using motion equation
x=vt+1/2at^2

A car accelerates from rest at a rate of 4 m/s’2 . How many seconds will it take the car to reach a final speed of 16m/s
Answer:
t = 4 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f}=v_{o}+a*t[/tex]
where:
Vf = final velocity = 16 [m/s]
Vo = initial velocity = 0
a = acceleration = 4 [m/s²]
t = time [s]
Now replacing:
[tex]16=0+4*t\\t = 16/4\\t = 4[s][/tex]

How much resistance allows 6V battery to produce a current of 0.006 amps?
Answer:
It produces 1000Ω.
Explanation:
You have to apply Voltage formula, V = I × R :
V = I × R
6 = 0.006 × R
R = 6 ÷ 0.006
R = 1000Ω
We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that How much resistance that allows 6V battery to produce a current of 0.006 amps is
R=1000 ohms
From the Question we are told
How much resistance allows 6V battery to produce a current of 0.006 amps?
Generally the equation for Resistance mathematically given as
[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]
R=1000 ohms

F = m x a. A ball of mass 0.35kg rolls on a smooth surface hits another object at rest and of mass 7kg. The second object gets an acceleration of 1.5m/s2. What acceleration does the ball get? Use newton’s third law.
Please show the working and thankyouu!!
Answer:
The acceleration the ball gets = 30 m/s²
Explanation:
The given parameters are;
The mass of the first ball that hits an object, m₁ = 0.35 kg
The mass of the object hit by the ball, m₂ = 7 kg
The acceleration given to the second object, a₂ = 1.5 m/s²
Let the a₁ represent the acceleration the ball gets
Newton's third law states that action and reaction are equal and opposite, therefore, the force exerted on a body A by a body B is equal to the force exerted on the body B by the body A;
Therefore, we have;
The force exerted on the object, F₂ = m₂ × a₂ = 7 × 1.5 = 10.5 N
The force the ball exerts on the object = F₁ = m₁ × a₁ = 0.35 × a₁
By Newton's third law, F₁ = F₂, which gives;
m₁ × a₁ = m₂ × a₂
0.35 × a₁ = 10.5
a₁ = 10.5/0.35 = 30
The acceleration the ball gets = a₁ = 30 m/s².
