Answer:
Captive animals are animals that are maintained by people in an enclosed place not allowing them to be free. There are several factors that make it difficult to reintroduce them to their natural habitats like:
-Captive animals don't learn the necessary skills to survive in their natural habitats like hunting skills.
-They are too used to have contact with people which makes them vulnerable to hunters.
-Sometimes these animals are not able to integrate with a wild population.
-It has been found that some captive animals are more susceptible to diseases.

Which of the following is NOT a vector quantity?
(A) Acceleration
(B) Average velocity
(C) Linear momentum
(D) Potential energy
(E) Force
Answer:
D
Explanation:
Acceleration has both magnitude and direction. because velocity is vector quantity
average velocity is vector
linear momentum = mass× velocity
therefore it's also vector
force = mass× acceleration
acceleration is vector therefore force also vector
potential energy= mgh
energy in any form is scaler quantity therefore potential energy too is a scaler quantity.

Together, two students exert a force of 825 N in pushing a car a distance of 35 m.
How much work do the students do on the car?
Answer:
28875 Joule
Explanation:
W = F * d
W = 825*35 = 28875 J
The work done by the students in pushing a car at a distance of 35 meters would be 28875 Joules.
What is work done?The total amount of energy transferred when a force is applied to move an object through some distance
The work done is the multiplication of applied force with displacement.
Work Done = Force * Displacement
As given in the problem Together, two students exert a force of 825 Newtons in pushing a car at a distance of 35 meters, then we have to find out the work done by the students,
The force exerted by the students = 825 Newtons
The distance moved by car = 35 meters
work done by students = 825×25
=28875 Joules
Thus, the work done by the students would be 28875 Joules.

In charging by rubbing, electrons move from one material to another because
A. substances with very few neutrons have a net positive charge, so
they get the extra electrons.
O B. heavier substances get rid of electrons so they don't weigh as
much.
O C. the substance with the most protons steals electrons from the
other substance.
O D. some substances hold onto electrons tighter than other
substances, so they get the extra electrons.
Answer: D.
some substances hold onto electrons tighter than other
substances, so they get the extra electrons.
Explanation: When two substances are in contact by rubbing each other, there will be friction between them. The friction will stimulate what we called - Thermal energy. And what thermal energy does is the disrupt the bonding force or enhance it.
We can therefore conclude that some substances hold onto electrons tighter than other substances, so they get the extra electrons. Because at neutral state of the substance, the number of protons is equal to the number of electrons.

Remembering the Battle of Bunker Hill what did general Howe and his troops do
Answer:
General Howe and the British regrouped after losing the hill.
Explanation:
British forces marched to Breed's Hill on 17 June under the order of Major General William Howe. When the British Army marched in waves toward the Americans, Colonel William Prescott issued orders to avoid the fire until British troops came to clear sight in an attempt to protect the dwindling supply of ammunition to the Americans. Many British soldiers have been killed or maimed; the remainder has withdrawn down the hill. In a second wave, the British stormed the hill once again but met with the same fate. So they withdrew again, suffering a large number of casualties. Eventually the British took the hill in the third attempt but at a great cost of casualties.

What is the mass of a 600 gram object on the moon
A car accelerates uniformly from 0 km/hr to 60 km/hr in 4.5 seconds. Which one of the following choices best represents the acceleration of the car?
(A) 13.3 m/s2
(B) 9.8 m/s2
(C) 4.8 m/s2
(D) 3.7 m/s2
(E) 0.37 m/s2
please show work
Answer:
The acceleration of the car is [tex]3.7\ m/s^2[/tex].
Explanation:
It is given that,
Initial speed of the car, u = 0
Final speed of the car, v = 60 km/h = 16.66 m/s
Time, t = 4.5 s
We need to find the acceleration of the car. It is equal to the change in velocity divided by time taken. It can be given by :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{16.66-0}{4.5}\\\\a=3.7\ m/s^2[/tex]
So, the acceleration of the car is [tex]3.7\ m/s^2[/tex]. Hence, this is the required solution.
Please help me find the last one ASAP! Thanks :))) (You don't have to send the definition)
10. Almost three-quarters of household energy use is due to the following:
• home furnaces and air conditioners
• water heaters
• washers and dryers
• lighting
For each of these uses of energy, give two reasonable ways to reduce household
energy consumption
Answer: Energy consumption and sustainability is important so that it remain available for future generation.
Explanation:
1. The home furnaces are likely to require fuel like coal, which will directly emit carbon dioxide and carbon monoxide gases. These should be replaced with the electrical furnaces. The old or more power consuming air conditioners should be replaced with new ones.
2. The water heaters should be tankless so their capacity to heat more water could be possible. The water heaters should be electricity saving.
3. Washer and dryers should be water savy and electricity savy. A front-loading washing machine is useful energy saver.
4. The LED lights are more electricity saving than conventional bulbs. Halogen lights are also electricity saving.
Please help me answer this question! Will appreciate help very much. a) Draw a circuit to show 3 lights in series b) Draw a circuit to show 2 lights in parallel c) Draw a circuit that shows 2 lights in parallel which are both in series with a third light. d) What would happen to the 2 other lights if the third light in question c) fails
Answer:
C kind sir
Explanation:
A washing machine heats 10kg of water in each wash cycle. How much energy is saved by washing at 30'c instead of 50'c if the starting temperature of the cold water is 16'c? The specific heat capacity of water is 4200 J/Kg'c
The two equations you can use is in the picture.
8.4 × 10⁵ Joules of heat energy can be saved assuming that there is no heat exchange between the washing machine and the environment.
What is Heat energy?Heat energy is the result of movement of tiny particles called as atoms, molecules, or ions in solids, liquids and gas substances. Heat energy can be transferred from one object to another object.
Let m denote the mass of water and the specific heat capacity of water. The energy required to raise the temperature of that much water by would be:
Q = m × c × ΔT
Washing at 30°C would require a temperature change of
ΔT = 30°C - 16°C = 14°C
Washing at 50°C would require a temperature change of
ΔT = 50°C - 16°C = 34°C
In both situations, c = 4.2 × 10³J.kg/ °C while m = 10kg.
Calculate the energy required in either of the situations as:
Washing at 30°C:
Q(30°C) = c × m × ΔT
Q = 4.2 × 10³J.kg/ °C × 10kg × 14°C
Q = 588000 Joules
Washing at 50°C :
Q (50°C) = c × m × ΔT
Q = 4.2 × 10³J.kg/ °C × 10kg × 34°C
Q = 1428000 Joules
1428000 Joules - 588000 Joules = 8.4 × 10⁵ Joules

Ax = 44.4 m and Ay = 25.1 m Find the direction of the vector.
Answer: 29.5 degree
Explanation: Given that
Ax = 44.4 m and Ay = 25.1 m
The direction of the vector will be
Tan Ø = Ay/Ax
Substitute Ay and Ax into the formula
Tan Ø = 25.1/44.4
Tan Ø = 0.5653
Ø = tan^-1(0.5653153)
Ø = 29.48 degree
Ø = 29.5 degree approximately.
Therefore, the direction of the vector is 29.4 degrees approximately.

OA
An object accelerates in the direction opposite to the direction of the force applied.
ОВ.
An object accelerates in the direction perpendicular to the direction of the force applied.
Ос. An object accelerates in the same direction as that of the force applied.
OD An object undergoes no acceleration on the application of force.
O E. An object's acceleration is independent to the force applied.
Answer: I think is OA.
Refer:
Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. In equation form, Newton's second law of motion is a=Fnetm a = F net m .
Light travels approximately 982,080,000 ft/s, and one year has approximately 32,000,000 seconds. A light year is the distance light travels in one year.
Calculate the distance of one light year in feet.
Answer: 3.142656 × 10^16 feet
Explanation: Given that the
Speed = 982,080,000 ft/s, and
Time = 32,000,000 seconds
The formula for speed is:
Speed = distance/ time
Make distance the subject of formula
Since the time is second in one year and speed is ft/s, substitute both into the formula
Distance = speed × time
distance = 982,080,000 × 32,000,000
Distance = 3.142656 × 10^16 feet.
The distance of one light year in feet is 3.142656 × 10^16
