Please help !! I have no clue how to do this
Answer:
THIS IS SUPER EASY!!!!!!
BOLD = ANSWER
Explanation:
REMEMBER: force = mass x acceleration
4. 6.0kg x 4.0m/s2 = 24N
5. 7.5kg x 8.3m/s2 = 62.25N
6. 2,000kg x 8.3m/s2 = 16,000N
REMEMBER: mass = force / acceleration
7. 6.0N / 3.0m/s2 = 2kg
8. 6.0N / 12.0m/s2 = 0.5kg
9. 20.0N / 5.0m/s2 = 4kg
10. 20.0N / 2.0m/s2 = 10kg
11. 4.0N / 7.3m/s2 = 0.55kg
12. 4.6N / 16.3 m/s2 = 0.28kg

Norma drives her car for 150 min at 40 km/h, then rests for 75 min, and then drives for 3.15 h at 60 km/h. What was Norma’s average speed?
Answer:
Norma’s average speed is 41.9 km/h.
Explanation:
The average speed is given by:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} [/tex]
Where:
[tex]d_{T}[/tex]: is the total distance
[tex]t_{T}[/tex]: is the total time
We can find the total distance as follows:
[tex] d_{T} = v_{1}*t_{1} + v_{2}*t_{2} = 40 \frac{km}{h}*150 min*\frac{1 h}{60 min} + 60 \frac{km}{h}*3.15 h = 289 km [/tex]
Now, the total time is:
[tex] t_{T} = t_{1} + t_{2} + t_{3} = 150 min*\frac{1 h}{60 min} + 75 min\frac{1 h}{60 min} + 3.15 h = 6.9 h [/tex]
Hence, the average speed is:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} = \frac{289 km}{6.9 h} = 41.9 km/h [/tex]
Therefore, Norma’s average speed is 41.9 km/h.

What is the process of satellite orbiting?The goal of satellites is to achieve balance. They rotate around the globe quickly enough to avoid being entirely drawn down into the planet's center of gravity, yet slowly enough to avoid drifting out into space.
When a satellite is travelling at the right speed, the earth's gravitational attraction is just strong enough to keep it in place. A satellite must move quicker to maintain orbit the nearer it is to the earth's surface. Additionally, satellites' orbits are circular or elliptical due to the continual pull of the curved surface of the planet.
Therefore, gravity plays a crucial role in our daily lives, whether it's keeping us anchored to the planet's surface or keeping the satellites we use to communicate and learn more about our environment in orbit.

A team of students uses a Bunsen burner to heat a beaker full of ice and uses a thermometer to measure the temperature of the sample as it heats. Their data indicate that the ice maintains a constant temperature of 0°C. Which of the following could be occurring? Select all the options that apply.
Answer:
1. The ice molecules are at a temperature of 0°C;
2. The ice molecules are absorbing latent heat which would result in their turning to liquid water. Therefore, melting or fusion is occurring.
Note: The question did not provide any options to choose from.
Explanation:
The process of change of state occurs when heat is added or removed from a substance. For example, solid may change to a liquid when heat is added to it whereas a liquid may change to liquid when heat is removed from it.
During the process of change of state, the temperature of the substance undergoing a change of state does not change throughout the time it is undergoing the change. The temperature will begin to increase or decrease when all the molecules of the substance has undergone a change of state. The heat supplied to or removed from a substance during a change of state is known as latent heat.
When a solid changes to liquid, it is known as fusion and the heat absorbed by the solid substance is known as latent heat heat of fusion. If a liquid changes to gas, it is known as vaporization and the heat absorbed by the liquid is known as latent heat of vaporization.
In the experiment by the students above, since the temperature of the ice remains constant at 0°C when heat is supplied from the Bunsen burner to it, the following processes could be occurring:
the ice is at a temperature of 0°C;the ice molecules are absorbing latent heat which would result in their turning to liquid watermelting or fusion is occurringAnswer: B, C, D

According to Mendel's law of segregation, what takes place during meiosis?A.Pairs of alleles cross over on chromosomes, exchanging one for anotherb.Pairs of alleles separate in meiosis, and each gamete receives one allele of a pairc.Part of an allele is separated, or broken off, from its chromosomed.One chromosome is suppressed, and the other chromosome of the pair determines the traits of the offspring
Answer:
b. Pairs of alleles separate in meiosis, and each gamete receives one allele of a pair.
Explanation:
Gregor Mendel, who is referred to as the FATHER OF GENETICS because of his contribution to the principles of inheritance, proposed in one of his laws called LAW OF SEGREGATION that the alleles of a gene will separate into gametes in such a way that only one of the two alleles that make up a gene will be in each gamete.
This division/separation of alleles during gamete formation is called MEIOSIS. Note that, allele is one member of a gene. Hence, according to Mendel, in meiosis, pairs of alleles separate and each gamete receives one allele of a pair.

what is the magnitude of the eletrostatic force on an electron by another electron when they are 0.10 meter apart?
Answer:
[tex]F=2.30\times 10^{-26}\ N[/tex]
Explanation:
The distance between two electrons, d = 0.10 m
We need to find the magnitude of the electrostatic force on an electron by another electron.
The electrostatic force between two charges is given by :
[tex]F=k\dfrac{q_1q_2}{d^2}[/tex]
Substitute all the values,
[tex]F=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(0.1)^2}\\\\F=2.30\times 10^{-26}\ N[/tex]
So, the magnitude of the electrostatic force between two electrons is [tex]2.30\times 10^{-26}\ N[/tex].
It is a force imposed by one charge on another as a result of the field. The magnitude of the electrostatic force will be 2.30×10⁻²⁶N.
What is the electrostatic force?
It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge is inverse of the square of the radius.
The electrostatic force is determined by the charge potency of each charge as well as the separation distance between them.
The given data in the problem is;
q=q₁=q₂ is the electric charge = 1.6×10⁻¹⁹C
r is the distance between the two charge=0.10 m
The formula for the electrostatic force is given by;
[tex]\rm F=\frac{ Kq_1q_2}{r^2} \\\\ \rm F=\frac{ 9\times 10^9 \times(1.6\times 10^{-19})^2}{(0.1)^2}\\\\ \rm F =2.30 \times 10^{-26} \ N[/tex]
Hence the magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

You push a box at a constant speed of 5m/s and let it go. It stops 1.5s later due to the force of friction. If you push the box at a speed of 12m/s, how long will it take to stop?
Answer:
the time taken for the box to stop is 3.6 s.
Explanation:
Given;
initial speed with which the box was pushed, u = 5 m/s
time taken for the box to stop, t = 1.5 s
Assuming the box is moving at constant acceleration, a;
[tex]a = \frac{u}{t} \\\\a = \frac{5}{1.5} \\\\a = 3.33 \ m/s[/tex]
When the box is pushed a speed of 12 m/s, the time taken for the box to stop is calculated as;
[tex]t = \frac{v}{a} \\\\t = \frac{12}{3.33} \\\\t = 3.6 \ s[/tex]
Therefore, the time taken for the box to stop is 3.6 s.
A car is traveling in a race.The car went from the initial velocity of 35 to the final velocity of 65 in 5 seconds what is the acceleration
Answer:
Acceleration = 6m/s²
Explanation:
Given the following data;
Initial velocity = 35m/s
Final velocity = 65m/s
Time = 5 seconds
To find the acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]t is time measured in seconds.Substituting into the equation, we have
[tex]a = \frac{65 - 35}{5}[/tex]
[tex]a = \frac{30}{5}[/tex]
Acceleration = 6m/s²
