Answer:
Gravity
Explanation:
Gravity is a force that acts upon every single object on Earth.
A toy rocket has a mass of 2.0 kg. The rocket has a force of 8.0 N acting on it. What is the acceleration of the rocket?
6.0 m/s^2
0.25 m/s^2
16.0 m/s^2
4.0 m/s^2
Answer:
force=mass × acceleration
8=2 × acceleration
acceleration= 8/2= 4 m/s²
Answer:4 m/s²
Explanation:
How many seasons are there in a year
Answer:
There are 4
Explanation:
Many vehicles leave the right shoulder of the pavement due to
brake failure.
improper interior inspections.
driver distraction.
lack of oil pressure.
Answer:
driver distraction
Explanation:
Studies and historical data show that the major cause of this is due to driver distraction. When driving many times a driver may look somewhere other than the road and get distracted which accidentally causes the driver to steer outside of the right shoulder of the pavement. This can also be due to the driver becoming tired/sleepy after driving for countless hours or even making a quick maneuver due to oncoming traffic getting too close. Regardless, all of these fall under driver distraction.

You push on a light object (small mass) with a certain amount of force and it moves. If you push just as hard on a heavier object (large mass) it will move _____ the light object. a. Faster than b. slower than c. the same as
Answer: B
Explanation:
It will move slower than the light the object. The equation is Newton's 2nd Law of F = ma. If the force is constant, and the mass changes to something larger, then the acceleration must become smaller. You could also just do this yourself, push two objects with your hands. The heavier one will move slower assuming you used the same amount of force
What is the mass of an object that requires 150N of force in order to accelerate it at 10m/s 2
Answer: 15kg
Explanation:
F = ma ; Newtons 2nd of Motion
150 = m(10)
m = 15kg
Please help ASAP please
Answer:
I would say 3N

A force of 162 N is applied to an object causing it to accelerate at a rate of 3.8 m/s^2. What is its mass?
A. 0.2 kg
B. 616 kg
C. 43 kg
D. 102 kg
Answer:
43 kg
Explanation:
Force (F) = 162 N
acceleration (a) = 3.8 m/s²
mass (m) = ?
We know
F = m * a
162 = m * 3.8
m = 162 / 3.8
m = 43 kg
It's mass is 43 kg.
Hope it will help you :)

How do electromagnetic fields work?
Answer:
Electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.
please help answer question
Answer:
C = 1.01
Explanation:
Given that,
Mass, m = 75 kg
The terminal velocity of the mass, [tex]v_t=60\ m/s[/tex]
Area of cross section, [tex]A=0.33\ m^2[/tex]
We need to find the drag coefficient. At terminal velocity, the weight is balanced by the drag on the object. So,
R = W
or
[tex]\dfrac{1}{2}\rho CAv_t^2=mg[/tex]
Where
[tex]\rho[/tex] is the density of air = 1.225 kg/m³
C is drag coefficient
So,
[tex]C=\dfrac{2mg}{\rho Av_t^2}\\\\C=\dfrac{2\times 75\times 9.8}{1.225\times 0.33\times (60)^2}\\\\C=1.01[/tex]
So, the drag coefficient is 1.01.

TRUE or FALSE: An object's mass changes depending on which planet it is located.
A. TRUE
B. FALSE
Answer:
Fales
Explanation:
That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.
Which kind of force(s) cause acceleration?
Answer:
unbalanced force,
Explanation:
The bigger the unbalanced force acting on the object the bigger the acceleration of the object. The more mass the object has, the more inclined it is to resist any change to its motion.
What happens to the position of an object as an unbalanced force acts of it? Give an example
Answer:
When unbalanced forces act on an object at rest, the object will move. ... Second, when unbalanced forces act on a moving object, the velocity of the object will change. Remember that a change in velocity means a change in speed, direction or both speed and direction.........Eg.If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it.
Answer:
unbalanced forces could change speed,direction
Explanation:
Example
if two people are pulling a rope and the other one is stronger the rope moves toward the stronger one cause the force is unbalanced

Which force stops the car from moving?
The force of motion
The force of speed
The force of gravity
The force of Friction
Answer:
The force of friction.
Explanation:
Gravity keeps the car on the ground.
Motion Allows the car to move.
The force of speed doesnt make sense.
Friction would cause the car to stop moving.

Clara made a chart to summarize some of the evidence that supports the big bang theory.
A 2 column table with 2 rows labeled evidence for the big bang theory. The left column is labeled category of evidence with entries redshift, cosmic microwave background radiation (CMB). The second column is labeled description with entries light source and observer move farther apart, light observed shifts to a longer wavelength, indicates receding galaxies, red-shifted to the microwave region, temperature much higher now than at time of big bang.
Which best describes Clara’s error?
During redshift, the light source and observer move closer together, not farther apart.
The CMB is blue-shifted, not red-shifted, to the microwave region.
The temperature of the CMB is cooler, not hotter, than at the time of the big bang.
The redshift indicates approaching, not receding, galaxies.
Answer:
The temperature of the CMB is cooler, not hotter, than at the time of the big bang.
