Answer:
C
Explanation:
When the planet in motion should have the same speed so until it should be acted by an outer force. This statement explained the movement of the planets.
The information regarding the first law of motion is as follows:
In the case when the body is at rest or moves at the same speed on the straight line so it should be the same at rest or a movement until it is acted by an outside force. It is also called as law of inertia.Therefore, the third option is correct.

9. Bryce drove his car 10 km from his house to Belle Plaine. It took him 8 minutes. He got stopped at a long
traffic light on the return home and so he took 2 minutes longer on the return trip. What was Bryce's average
speed in km per minute? (3 pt)
Answer:
2 km/minuteExplanation:
Here, we are asked to calculate the average speed in km/minute.
As we know that,
Average speed = Total distance ÷ Total time takenHere,
→ Total distance = 10 km + 10 km
Because, he first drove 10 km from his house to Belle Plaine and then he again came back to his house.→ Total distance = 20 km
→ Total time = 8 minutes + 2 minutes
→ Total time = 10 minutes
Substitute the values in the formula of average speed,
→ Average speed = Total distance ÷ Total time taken
→ Average speed = 20km ÷ 10 minutes
→ Average speed = 2 km per minutecan someone please help me please I will mark brainlist and give you 5 stars pleasee

The force exerted by water and air on the skier is 50 Newtons (N) to the left. The force exerted by the boat on the skier is 40 Newtons (N) to the right. How will the unbalanced forces change the motion of the skier
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Net force on a body.
We know that net force on a body is the force that is calculated from all direction and added , if there is any force remained at last, then the forces are unbalanced,
and if the net force on a body is Zero, then it is a balanced force,
here,
Force to left on skier = 50 N
Force to right on skier = 40 N
hence the net force = left force - right force
Net force = 50 - 40 ==> 10 N
hence the Net force is 10 N in the left direction of the skier.

The diagram below shows a periodic wave. Which two points on the wave are 180 degrees out of phase?
Please explain as well, thanks so much
Answer:
A and C are 180 deg out of phase (opposite points on a 360 deg wave)
The two points on the periodic wave which are 180 degrees out of phase are point A and Point C.
When two points of wave are out of phase?The two points of a wave is said to be out of phase when they show up or down motion at different times.
If a point on the wave, say (X) is reached to the maximum or minimum point before the other point. Then these two points are said to be out of phase.
Also, when the points are 180 degree apart from each other. Which means if a point is in the crest of the wave and other is on the through.
The diagram below shows a periodic wave. In this diagram,
A and I are the end points of the periodic wave.B,C,D,E,F and G are the other points on the periodic wave.Here, the point A and C are opposite point of each other. So they are 180 degrees out of phase.Hence, the two points on the periodic wave which are 180 degrees out of phase are point A and Point C.

According to the graph, how many atoms would remain after two half-lives?
20 atoms
80 atoms
40 atoms
50 atoms
Answer:
Let No be initial no of atoms
N = N0 / 2 after 1 half-life
N = N0 / 4 after 2 half-lives
So after 2 half-lives 20 of the 80 atoms remain

How much work is done by 0.070 m3 of gas, when the volume remains constant with pressure of 63 x 105 Pa?
Answer:
W = 0 J
Explanation:
The amount of work done by gas at constant pressure is given by the following formula:
[tex]W = P\Delta V[/tex]
where,
W = Work done by the gas
P = Pressure of the gas
ΔV = Change in the volume of the gas
Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:
[tex]W = P(0\ m^3)\\[/tex]
W = 0 J
1- Three 6-ohms resistors in a series circuit give equivalent resistance of
Answer:
The equivalent resistance of the three resistors is 18 ohms.
Explanation:
The value of three resistors are 6 ohms.
We need to find the equivalent resistance of the resistors. In series combination, the equivalent resistance is given by :
R = R₁ + R₂ + R₃ +.....
Put all the values,
R = 6+6+6
R = 18 ohms
Hence, the equivalent resistance of the three resistors is 18 ohms.
Three 18-ohm resistors are connected in series with an ideal 12-volt battery. What is the equivalent resistance of the circuit?
Answer:
RT = 54 Ohms
Explanation:
Given the following data;
Resistance = 18 Ohms
Voltage = 12 Volts
To find the equivalent resistance (RT) of the circuit;
For a series connection, the formula is;
RT = R1 + R2 + R3
RT = 18 + 18 + 18
RT = 54 Ohms
Or
RT = 3*R
RT = 3 * 18
RT = 54 Ohms

What is the intensity of sound produced by an elephant's call if it has a power of 0.45 W and you are standing 32.5 m away from the lumbering beast
Answer:
I = 1.36 x 10⁻⁴ W/m²
Explanation:
The intensity of the sound produced by the Elephant can be calculated by using the following formula:
[tex]I = \frac{P}{A} \\\\[/tex]
where,
I = Intensity of sound = ?
P = power of sound = 0.45 W
A = area = πr² = π(32.5 m)² = 3318.3 m²
Therefore,
[tex]I = \frac{0.45\ W}{3318.3\ m^2} \\\\[/tex]
I = 1.36 x 10⁻⁴ W/m²
Which is not true about the role of gravity in the formation of planets?
Dust and gas particles that were attracted to each other began to rotate into a protoplanetary disk.
Gravity between planetesimals caused them to join together into conglomerate clumps. Our solar system is the only place in the universe where gravity played a key part in the formation of planets.
Gravity of larger objects in orbit around the sun attracted, and cleared the orbital path of, smaller planetesimals, gas, and dust.
Our solar system is the only place in the universe where gravity played a key part in the formation of planets.

What is the difference between the spectrum of an incandescent solid and the spectrum of an incandescent gas?
Incandescent solids emit bright-line spectra; incandescent gases emit continuous spectra.
Incandescent solids emit one wavelength; incandescent gases emit several wavelengths.
Incandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
Incandescent solids emit scattered spectra; incandescent gases emit continuous spectra.
Answer:
ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
Explanation:
Materials when heated emit a continuous spectrum with all wavelengths.
Hot gas gases emit a spectrum that depends on the transitions between atomic states, therefore it is a discrete spectrum.
When reviewing the answers, the correct one is:
ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
The bumper cars crash into each other and stop. Explain why both bumper cars stop after the crash. [4marks]
Answer:
The collision is inelastic
Explanation:
There are two kinds of collision; elastic collision and inelastic collision. In an elastic collision, both momentum and kinetic energy are conserved.
However, in an inelastic collision, kinetic energy is not conserved. So, when the bumper of two cars collide, the cars come to a stop because the collision is inelastic.
