Answer:
Elastic goods and services generally have plenty of substitutes. As an elastic service/good's price increases, the quantity demanded of that good can drop fast. Example of elastic goods and services include furniture, motor vehicles, instrument engineering products, professional services, and transportation services.
Explanation:
elasticity of supply measures the responsiveness to the supply of a good or service after a change in its market price. According to basic economic theory, the supply of a good will increase when its price rises. Conversely, the supply of a good will decrease when its price decreases.

A circuit has a current of 3 A. How many coulombs of charge will pass by a point in the circuit in 2 seconds?
- 6C
- 5C
- 3/2 C
- 2/3 C
One of these are the answer..
6C
Explanation:
The quantity of charge, Q, passing through an electric circuit is dependent on the electric current, I, and the time taken, t, for the current to flow. It is given mathematically as follows
Q = I x t ------------------------------(i)
Where;
I is measured in Amperes(A)
t is measured in seconds (s)
Q is measure in coulombs (C)
From the question,
I = 3A
t = 2s
Substitute these values into equation (i) as follows;
Q = 3 x 2
Q = 6C
Therefore, the number of coulombs of charge that will pass is 6C

A pendulum is swinging back and forth with a period of 2.0 seconds here on Earth. This pendulum is then brought to the Moon, where the acceleration due to gravity is much smaller. What will happen to the period of the pendulum, assuming everything else about it (mass, length, initial swing height, etc) remains exactly the same
Answer: The period will be larger, with T = 4.92 seconds
Explanation:
The period of a pendulum can be obtained by the equation
T = 2*pi*√(L/g)
Where pi = 3.14, L = lenght of the pendulum and g = gravity acceleration.
You can see that the gravitational acceleration is on the denominator, this means that if we decrease the value of g, then the value of T will increase.
In Earth we have that:
2s = 2*3.14*√(L/9.8m/s^2)
L = (1/3.14)^2*9.8 m = 1m
In the moon we have g = 1.62 m/s^2
then the period in the moon is:
T = 2*3.14√(1/1.62) = 4.92s

A skier reaches the end of a 0.9 km track in 1.5 hours, at what speed does it travel?
(Please help,I need the answer as soon as possible)
Speed = Distance/Time
S = D/T
D = 0.9Km, T = 1.5hours,
S = 0.9/1.5
S = 0.6 m/s
hope it helps!
Answer: Speed =
distance = 0.9 * 1000 = 900 metres, because speed is measured in m/s so the km has to be converted to m
time = 1.5 * 60 = 90 seconds , because speed is measured in m/s so the time in minutes(m) has to be converted to seconds(s)
Speed =

The word gymnosperm comes from two Greek words: gymno, meaning bare, and sperm, meaning_____ . Unlike other seed plants, gymnosperms do not have a protective _______ around their seeds. Most gymnosperms have needle-like or scale-like ______.
Answer:
Seed, Fruit, Leaves
Explanation:
Gymno, meaning bare, and sperm, meaning seed. Unlike other seed plants, gymnosperms do not have a protective fruit around their seeds. Most gymnosperms have needle-like or scale-like leaves.
What are gymnosperms?A relatively tiny class of plants known as gymnosperms produce seeds and lack flowers. This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
Gymnosperm can also be referred to by the less common word acrogymnospermae. It's a broad name for plants like conifers, ginkgo, cycads, and gnetophytes that you probably already know about. The word "gymnosperm" has Greek roots. The tube cell, the generative cell, and two prothallial cells make up the gymnosperm pollen grain's four cells.
Conifers make up the majority of the plant species in the gymnosperm family. In contrast to angiosperms, which produce flowers, gymnosperms create cones as their reproductive organs. Gymnosperms primarily consist of conifers, such as pine trees.

A 1200 kg car accelerates from 13m/s to 17m/s. find the change in momentum of the car?
Answer:
4800
Explanation:
The change in velocity of the car is 17-13=4m/s. Since the change in momentum is the mass multiplied by the change in velocity, the answer is 4*1200=4800. Hope this helps!
Given:
Mass,
m = 1200 kgChange in velocity,
Δv = 17-13= 4 m/s
Now,
The change in momentum is:
= [tex]Mass\times Change \ in \ velocity[/tex]
= [tex]1200\times 4[/tex]

On a sky coaster (human pendulum) that reaches 20 meters from it's equilibrium position, a man of 70 kg is able to reach a maximum speed of
Answer:
Explanation:
Using the principle of conservation of energy, the potential energy is converted to kinetic energy, assuming any losses.
Kinetic energy is given by ½mv²
Potential energy is given by mgh
Where m is the mass, v is the velocity, g is acceleration due to gravity and h is the height.
Equating kinetic energy to be equal to potential energy then
½mv²=mgh
V
Making v the subject of the formula
v=√(2gh)
Substituting 9.81 m/s² for g and 20 m for h then
v=√(2*9.81*20)=19.799 m/s
Rounding off, v is approximately 20 m/s
Answer:
19.8 m/s
Explanation:
During the motion of a pemdulum bob, it casually converts kinetic energy to potential energy and vice versa.
A pendulum bob reaches its maximum speed at a position closest to its equilibrium position and has its lowest when it is farthest from the equilibrium position.
The maximum speed of a pendulum bob based on the mass involved and the maximum displacement from the equilibrium position is obtained from
Maximum kinetic energy = Maximum potential energy
Maximum potential energy occurs at the farthest point from equilibrium, that is,
P.E(max) = mgh
Maximum kinetic energy = ½mv²
½mv² = mgh
v = √2gh
g = acceleration due to gravity = 9.8 m/s²
h = farthest height from equilibrium position = 20 m
v = √(2×9.8×20) = 19.8 m/s
Hope this Helps!!!
Se tienen 2 vectores cuyos módulos están en la misma razón que 5 y 2. Si cuando forman 53º su resultante mide 3√29u, ¿Cuánto mide el mayor vector?
Answer:
|v2| = 3.27
Explanation:
You have two vector v1 and v2. The relation between the magnitudes of both vectors is given by:
[tex]\frac{|v_1|}{|v_2|}=\frac{5}{2}[/tex]
Furthermore, the projection (the dot product) of one vector on the other one is given by the following formula:
[tex]v_1 \cdot v_2 = |v_1||v_2|cos\theta[/tex]
The dot product between v1 and v2 is 3√29. If you multiply the right hand side of the last equation by |v2|/|v2| you obtain:
[tex]3\sqrt{29}=\frac{|v_1|}{|v_2|}|v_2|^2cos(53\°)[/tex]
you do |v2| the subject of the formula:
[tex]|v_2|=\sqrt{\frac{|v_2|}{|v_1|}\frac{3\sqrt{29}}{cos53\°}}\\\\|v_2|=\sqrt{\frac{2}{5}\frac{3\sqrt{29}}{cos53\°}}=3.27[/tex]

Trees are being felled at an alarming rate by people. Forests are home to numerous animals and people, and by removing trees from them, we are destroying their habitat and depriving them of a safe haven.
What is community conservation?Community conservation refers to a strategy for protecting the environment that acknowledges local residents' rights to manage wildlife or gain both direct and indirect benefits from it.
The gorillas' habitat, the forest, is being destroyed by humans. Additionally, people are harming these creatures, and if this continues, gorillas may become extinct.
There won't be as many resources from trees, like paper, if people cut down less of them, therefore prices could rise.
Prices for tourists will increase if fewer gorillas are still alive. That won't benefit visitors since they will have to pay more, and since some individuals don't have a lot of money, there will be fewer visitors.
Thus, this way, community conservation is mandatory.
