Answer:
there are a number of types of asexual reproduction including fission, fragmentation, budding, vegetative reproduction, spore formation and gamogenesis. Spore formation occurs in plants, and some algae and fungi, and will be discussed in additional concepts
the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female)
The advantages of sexual reproduction: produces genetic variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease is less likely to affect all the individuals in a population.

empty space
Answer:
empty space
Explanation:
Our solar system comprises of the sun as the star, the planets, the dwarf planets, various moons, and plenty of asteroids, comets, and meteoroids. However, the majority part of the solar system consists of a void or empty space. These empty spaces basically composed of planetary dust and gas.

A car traveled 885mi from El Paso, TX to Dallas, TX in 12.5 hours. What was the car's average speed?
Answer:
The car's average speed is 70.8 mph
Explanation:
The given parameters are;
The total distance traveled = 885 miles
The time of travel = 12.5 hours
The average speed is given by the following equation;
[tex]Average \ speed = \dfrac{Total \ Distance \ traveled}{Total \ time \ taken \ to \ travel \ the \ distance}[/tex]
Therefore, we have;
[tex]Average \ speed = \dfrac{885 \ miles}{12.5 \ hours} = 70.8 \ miles \ per \ hour[/tex]
Therefore, the car's average speed = 70.8 mph.
Answer:
The car's average speed is 70.8 mph

Explanation:
Shows a car travelling around a bend in the road. The car is travelling at a constant speed. There is a resultant force acting on the car. This resultant force is called the centripetal force. (i) In which direction, A, B, C or D, does the centripetal force act on the car? Tick ( ) one box. A B C D (1) (ii) State the name of the force that provides the centripetal force.
Answer:
This question is incomplete
Explanation:
This question is incomplete but the missing figure is in the attachment below.
When an object is travelling around a circular path, there is a force that tends to draw that object towards the center of the circular path and keep the object moving in the curved path, that force is called the centripetal force. From this description, it can be deduced that the direction of the centripetal force that acts on the car (in the attachment below) is D.
The name of the force that provides this centripetal force is frictional force. This is the force that prevents the car from slipping off the road; keeping it moving in the curved path.
Give one example where friction is useful. Can someone feed me with correct answer pls c:
Answer:
Friction is what holds your shoe to the ground. The friction present on the ice is very little, this is the reason why it is hard to walk on the slippery surface of the ice.
Explanation:
A car traveling with 500,000 J of kinetic energy is brought to a kinetic energy of
100,000 J in 12 seconds. What is the force acting on the car to accomplish this?
A:41,666.67
B:3x10^-5N
C:33,333.33N
D:8,333.33N
Answer:
33,333.33 N
Explanation:
Given that :
Initial kinetic energy = 500,000 J
Final kinetic energy = 100,000 J
Using the relation :
Force * time = change in momentum (Newton's law)
Force (F) * 0.12 = (500,000 - 100,000)
0.12F = 400,000 J
Force = (400,000 J) / 0.12s
Force = 33333.333
Force = 33,333.33 N

In May 1990 the French TGV train traveled the distance from Paris to Lille, France (127 miles) in 0.819 hours. What was the speed of the TGV in m/s
Answer:
v=69.32 m/s
Explanation:
you have to transfer the distance from mile to meters (from miles to meters multiply by 1609)
so d=204387 m
you have to transfer the time from hour to second (from hour to second multiply by 3600)
so t=2948.4 s
the rule says v=d/t=204387/2948.4= 69.32 m/s
The TGV train has a speed of 69.306 meters per second.
Let suppose that TGV train is travelling at uniform velocity, then we can be calculated its speed by means of the following kinematic equation:
[tex]v = \frac{x}{t}[/tex] (1)
Where:
[tex]v[/tex] - Speed, in meters per second.[tex]x[/tex] - Distance travelled by the train, in meters.[tex]t[/tex] - Time, in seconds.Now we proceed to convert both distance and time in terms of fundamental units:
Distance:
[tex]x = 127\,mi \times 1609\,\frac{m}{mi}[/tex]
[tex]x = 204343\,m[/tex]
Time:
[tex]t = 0.819\,h \times 3600\,\frac{s}{h}[/tex]
[tex]t = 2948.4\,s[/tex]
If we know that [tex]x = 204343\,m[/tex] and [tex]t = 2948.4\,s[/tex], then the speed of the TGV train is:
[tex]v = \frac{204343\,m}{2948.4\,s}[/tex]
[tex]v = 69.306\,\frac{m}{s}[/tex]
The TGV train has a speed of 69.306 meters per second.

Why do you think it is colder during the winter than the summer?
Answer:
As the earth travels around the sun during the year it maintains this tilt. Because of this tilt, in the summer we (north of the equator) are slanted more directly towards the sun so it's hotter. In the winter, we're slanted away so the sun's rays are less direct, making it colder.

Body weight 7,056 kN. What is its mass?
Answer:
Explanation:
The formula for weight goes- Weight=Mass*Gravity
We need to re arrange the formula in order to find the mass
so, mass=w/g
~If the person is on Earth then we can substitue the official the value of gravity as 9.8m/s^2 (this value is fixed)
~ The weight given in this question is 7,056 kN , but we need the weight to be in Newtons for the formula to acc work. So converting 7,056 kN to newtons would give 7056000N. (Newton = Kilonewton * 1000)
Now all we need to do is compute these values-
M= 7056000/9.8
M=720000kg

Green light (520 nm) enters glass with n = 1.52. What is speed of light in the glass?
Answer:
1.97 * 10^8 m/s
Explanation:
Given that:
n = 1.52
Recall : speed of light (c) = 3 * 10^8 m/s
Speed (v) of light in glass:
v = speed of light / n
v = (3 * 10^8) / 1.52
v = 1.9736 * 10^8
Hence, speed of light in glass :
v = 1.97 * 10^8 m/s

A mover slides a refrigerator weighing 650 N at a constant velocity across the floor a distance of 8.1 m. The force of friction between the refrigerator and the floor is 230
N. Calculate the coefficient of friction between the floor & refrigerator.
Answer: The coefficient of friction is 0.35
Explanation:
We can write the friction force as:
F = N*μ
Where N is the normal force between the refrigerator and the ground, as the full weight of the refrigerator is acting on the ground, the normal force will be exactly equal to the weight of the refrigerator, then:
N = 650N
And μ is the coefficient of friction.
And for this case, the force is 230N, then we have:
F = N*μ
230N = 650N*μ
(230N/650N) = μ = 0.35
Notice that the distance did not matter for this calculation.

A parallel circuit is shown in the diagram above. In this case the current supplied by the battery splits up, and the amount going through each resistor depends on the resistance. If the values of the three resistors are: R1 = 82, R2=82, and R3 = 42, the total resistance is found by: 1/R = 1/8+1/8+ 1/4 = 1/2. This gives R = 22. With a 10 V battery, by V = 1 R the total current in the circuit is: I = V/R = 10/2 = 5 A. The individual currents can also be found using I = V/R. The voltage across each resistor is 10 V, so the resistance across R1 : 2.5A 1.25V 2.5V 1.25A
