Explanation:
The pod may be heavier or lighter than normal, depending on the number of
asteroid samples.
• Based on everyday experience, heavier objects are more difficult to move as
compared to lighter objects, which are easier to move
This pod moved differently because it was more massive. The kids in other missions were less massive, so the thursters stopped the pod. The thrusters were supposed to do stop the pod, but since it was more massive it only slowed. The force exerted by the thrusters wasn't great enough to stop the pod.
Complete the sentence using word balanced, normal or tension.

A car is moving down the street at 53km/h. A child suddenly runs into the street. If it takes the driver 0.75 sec to react and apply the brakes, how many meters will the car have moved before it begins to slow down? ANSWER IN METERS
Answer:
11.04m
Explanation:
Convert kilometers to meters: 53km/h x 1000 = 53,000m/h
Convert hours to seconds: 53m/h / 3600 =14.72m/s
14.72 (.75) = 11.04

A body is moving with a uniform acceleration of 2 m/s2. What does it mean?
Answer:
it means the velocity is changing.
the rate of change of velocity is acceleration
so it means the body is accelerated at 2m/s^2
It means that the body is moving, and getting faster and faster. At any time, it's moving 2 m/s faster than it was moving 1 second earlier.
how much work is required to increase a velocity of 4kg object by 8m/s?
Answer:
4kg=4000,8m=60 times 8 =480
4000 times 480 over 100 =19200
Predict the speed of a car after 10.0 s when the car’s speed follows
the relationship speed = (4.8 m/s2 ) × (time).
Answer:
48 m/s
Explanation:
The time is 10 seconds
The speed of the car after 10 seconds when the relationship is 4.8 m/s^2 × time can be calculated as follows
= 4.8 × 10
= 48
Hence the speed is 48 m/s
Starting from rest, a car takes 2.4s to travel 15m. Assuming a constant acceleration, how long will it take the car to travel the next 15m?
Answer:
T = 2.4 + 2.4 = 4.8 [s]
Explanation:
In order to solve this problem, we must use the following kinematics equation and calculate the acceleration value.
[tex]x=x_{o} +v_{o}*t+(\frac{1}{2})*a*t^{2}[/tex]
Vo = inital velocity = 0
x - xo = 15 [m]
t = time = 2.4 [s]
15 = 0.5*a*(2.4)^2
a = 5.208 [m/s^2]
We can use the same equation to find the time.
30 = 15 + 0.5*(5.208)*t^2
t = 2.4 [s]
T = 2.4 + 2.4 = 4.8 [s]
A train on a straight track goes in the positive direction for 5.9km and then back up for3.8km. What is the train's displacement, what is the total distance covered by the train?
Answer:
Trains displacement = 2.1 KM
Total distance covered by the train = 9.7 KM
Explanation:
Total distance covered by train will be the total distance moved train
hence
total distance covered by the train = distance covered by train in positive direction + distance covered by train in moving back
total distance covered by the train = 5.9 KM + 3.8 KM = 9.7 KM
_____________________________________
Displacement is the shortest distance from original position to the final position during the course of movement of any object.
Given that
Train moved 5.9 KM in positive direction(let it be AB as shown)
hence displace until now is 5.9 KM
but it again moved back for 3.8 KM(let it be B to C as shown below)
it means , train moved 3.8 KM towards origin position
so net displacement will be = 5.9 KM - 3.8 KM = 2.1 KM
A............................................................B ----> 5.9 KM
A_________C___________________B
3.8 KM
Thus, AC will be displacement = AB - BC = 5.9 KM - 3.8 KM = 2.1 KM
Thus,
Trains displacement = 2.1 KM
Total distance covered by the train = 9.7 KM

Joyce and Efua are skating. Joyce pushes Efua, whose mass is 40.0 kg, with a force of 5.00 N. What is Efua’s resulting acceleration?
Answer:
[tex]a=0.125\ m/s^2[/tex]
Explanation:
Given that,
Mass, m = 40 kg
The net force with which Joyce pushes Efua is 5 N.
We need to find Efua’s resulting acceleration. Let it is equal to a. Net force is given by :
F = ma
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{5\ N}{40\ kg}\\\\a=0.125\ m/s^2[/tex]
So, the acceleration is [tex]0.125\ m/s^2[/tex].
The resulting acceleration of Efua is [tex]0.125 \;\rm m/s^{2}[/tex].
Given data:
The mass of Efua is, m = 40.0 kg.
The magnitude of applied force by Joyce is, F = 5.00 N.
The given problem is based on the Newton's Second law of motion. As per the Newton's second law, the applied force is equal to the product of mass and the acceleration of object. Therefore,
F = ma
a = F/m
Solving as,
a = 5.00 / 40
[tex]a = 0.125 \;\rm m/s^{2}[/tex]
Thus, we can conclude that the resulting acceleration of Efua is [tex]0.125 \;\rm m/s^{2}[/tex].

If this wave has frequency of 15 hz. what is the wavelength of that wave ?
If this wave has a frequency of 15 Hz then the wavelength of the wave would be 2 ×10⁷ m
What is Wavelength?It can be explained in terms of the separation between any two similar successive points on a wave, such as how the wavelength can be determined by calculating the separation between any two successive crests.
According to the following relation, the wavelength and wave frequency are inversely proportional.
C = νλ
Where c is the speed of light and v is the wave's frequency and λ
is the wave's wavelength.
As given in the problem If this wave has a frequency of 15 hz.
As we know C = νλ
by substituting the value of the frequency in the given formula
C = 3×10⁸ m/s
3×10⁸ = 15 ×λ
λ = 3×10⁸/ 15
= 2 ×10⁷ m
Thus, If this wave has a frequency of 15 Hz then the wavelength of the wave would be 2 ×10⁷ m

What is the charge of an element that has 5 protons and 7 electrons?
Answer:
atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.
Explanation:
When the amount of electrons in an atom is the same as the atomic number, the atom has a neutral charge. Particles with extra protons or missing electrons are known as ions.
Where is the electron?Electrons are present outside the electron shell, in contrast to nucleons, which are contained inside the core at its center. Neg electrons are drawn to a positive nucleus so because excitons of opposite polarity attract one another. The total energy of an electron is inversely proportional to the intensity at which the electrons wave equation vibrates. Elevated atomic states have faster-vibrating electrons. An electron should always be oscillating at some speed because it is a subatomic object with wave-like characteristics.
Why are electrons so important?Electrons are fundamental to many physical processes, including gravity, magnetic interactions, weak interrelations, electricity, magnetism, chemistry, and thermal conductivity. Ions and electrons are drawn into positive charges atoms by their nucleus's attraction pull. Unless an electrons received sufficient power to overcome this pressure by ascending, it was impossible for an electrons to escape from in an atom in mathematical mechanics.

which equation correctly represents the gravitational potential energy of a system?
Answer:ME= 1\2mv^2 + mgh
Explanation: I hope this helped.
The correctly represents the gravitational potential energy of a system is = - ΣGM₁M₂/R. Negative sign appears as gravitational force is attractive force.
What is potential energy?Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases.
If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised.
Potential energy is a characteristic of systems rather than of particular bodies or particles; for instance, the system made up of Earth and the elevated ball has more potential energy as they become further apart.
Potential energy of a system of particles can be represented as summation of individual's potential energy. Hence, the correctly represents the gravitational potential energy of a system is = - ΣGM₁M₂/R.

A certain space heater that is connected across 220 V and dissipates 1477 W of power in the form of electromagnetic radiation. What is the resistance of the heater?
Hi there!
We can use the power equation:
[tex]P = \frac{V^2}{R}[/tex]
P = Power (W)
V = Potential Difference (V)
R = Resistance (Ω)
Rearrange to solve for Resistance:
[tex]R = \frac{V^2}{P} = \frac{220^2}{1477} = \boxed{32.769 \Omega}[/tex]
