Answer:
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Objects 1 and 2 attract each other with a electrostatic force of 36.0 units. If the charge of Object 1 is doubled, then the new electrostatic force will be units.
If the charge on the object is doubled then the new electrostatic force is 72 units.
What does the term "electrostatic force" mean?Non-contact forces, such as electrostatic forces, pull or push on objects without actually making contact with them. When certain materials are rubbed together, a phenomenon known as "charge" can be transferred from one surface to another. Uncharged items are pulled by charged objects, which in turn may push or pull against other charged ones.
Let q and Q represent the charges on objects 1 and 2, respectively.
Charge Q is separated from charge q by a distance r, and their electrostatic attraction is given by:
F = kqQ/r²
where k is Coulomb's constant
According to the question:
F = 36 units
⇒ kqQ/r² = 36 units
Now, the charge on object 2 is doubled, so it now acquires a 2Q charge.
So the new electrostatic force will be:
F' = kq(2Q)/r²
F' = 2kqQ/r²
F' = 2F = 2×36
F' = 72 units

there is a metal ball and ring set that is specially made so that at room temperature at the ball fits through the ring However when the ball is heated it gets stuck and cannot fit through anymore .why
Answer: Most objects expand when they take in heat for example get a metal sphere and put it next to a blow torch it would expand just enough to not fit in the ring anymore, but when it cools down it will go back to its original size releasing the energy

A pendulum is swinging. It swings 85 complete swings and this takes 102 seconfs. What is the frequency? A. 0.83 Hz B.17Hz C.187 Hz D.1.2 Hz
Answer:
A: 0.83 Hz
Explanation:
Frequency can be calculated in a multitude of ways. The one way that is going to help you solve this problem is (# of times/seconds)
so you would divide 85 swings/102 seconds
= 5/6 or 0.8333 Hz
so your answer is A
1. A car travels along a straight road to the east for 100 meters in 4 seconds, then go the west for 50 meters in 1 second.
find the
a. Distance
b. Displacement
c. Time elapsed
Answer:
a.Distance = 150 m
b. Displacement = 50 m
Time lapsed = 5 seconds
Explanation:
a. Distance is the change in the position of an object.
The distance covered by the car = 100 + 50
= 150 m
b. Since displacement is a vector quantity,
Displacement of the car = 100 - 50
= 50 m due east
c. Time elapsed is the time taken for the motion of the car starting from when its starts to when it stops.
Thus, the time elapsed = 4 + 1
= 5 seconds

A body of mass 11 kg is subjected to a net force of 20 N East for 30 s. Calculate the change in
velocity of the body.
Answer:
54.55 m/s
Explanation:
From the question above,
Change in velocity = impulse/mass
Δv = I/m = Ft/m................... Equation 1
Where F = force, t = time, m = mass
Given: F = 20 N, t = 30 s, m = 11 kg
Substitute these values into equation 1
Δv = (20×30)/11
Δv = 600/11
Δv = 54.55 m/s
Hence the change in velocity of the body is 54.55 m/s
The change in velocity of the body is 54.54 m/s
The velocity of the body of an object is the change of the distance of the object with time.
From the information given:
the mass of the b0dy = 11 kg
the net force F = 20 N
the time (t) = 20 s
Similarly;
Force = ma
20 = 11 × (a)
[tex]\mathbf{a = \dfrac{20}{11} \ m/s^2}[/tex]
a = 1.818 m/s²
However, the acceleration of an object is the change in velocity with time.
[tex]\mathbf{a = \dfrac{\Delta V}{t}}[/tex]
ΔV = (a) × (t)
ΔV = 1.818 m/s² × 30 s
ΔV = 54.54 m/s

Describe how a radiation is similar to b- radiation
Complete question is;
Describe how α-radiation is similar to β-radiation?
Answer:
Explained below
Explanation:
The similarity between both alpha radiation and beta radiation is that in both cases, they both show deflection when they go through electric and magnetic fields. Although alpha deflects towards the negative plate while bets deflects towards the positive plate.
Secondly they both have high speeds. Just that alpha is from the helium nucleus while beta is from electrons.
And air rifle pellet of mass 2 g Is fired into a block of modelling clay mounted on a model railway track. The trunk and modelling clay have a mass of 0.1 kg the truck moves off after the pellet hits the modelling clay with an initial velocity of 0.8 m/s. State the momentum of the pallet just before it hits the modelling clay
Answer:
0.0816 kgm/s
Explanation:
From the question,
Momentum of the pellet just before it hits the modelling clay is = (mass of the pellet+ mass of the truck clay)×initial velocity of pellet.
P =(M+m)u...................... Equation 1
Where P = initial momentum of the pellet, m = mass of the pellet, u = initial speed of the pillet, M = mass of the truck
Given: m = 2 g = 2/1000 kg = 0.002 kg, u = 0.8 m/s, M = 0.1 kg
Substitute these values into equation 1
P = (0.002+0.1)0.8
P = (0.102)0.8
P = 0.0816 kgm/s

Which term describes the transfer of energy from a hot object to a cooler
one?
A. Pressure
B. Density
C. Temperature
D. Heat
Answer:
D
Explanation:
heat is an energy that transfers from a hot body to cold body
D. Heat
What is heat?Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object.
Such energy transfer can occur in three ways: radiation, conduction, and convection.
As heat is a form of energy, and therefore the SI unit of heat is also joules (J) which are defined as the amount of energy needed to raise the temperature of a given mass by one degree.
Heat is the transfer of energy from a warmer object to a cooler object.
For example, a lighted match (higher temperature object) will transfer heat to a large pan filled with lukewarm water (lower temperature object).
Therefore,
The term describes the transfer of energy from a hot object to a cooler one is Heat.

A car has 3600 J of kinetic energy and is going 3 m/sec. What is its mass?
Physics Help ASAP Please!
Answer:
23N
Explanation:
Answer:
9.3N
Explanation:
Fgrav = m • g = 14.7 N (g is 9.8 m/s/s)
a = v2 / R = (4 • Fgrav)/1 = 16 m/s/s
Fnet = m • a = 1.5 kg •16 m/s/s = 24 N, down
Fnet = Fgrav + Ftens, so
Ftens = Fnet - Fgrav
Ftens = 24 N - 14.7 N = 9.3 N
