Answer:
the answer is
Explanation:
constant acceleration
because when the object's velocity is changing then the object is accelerating or decelerating
as acceleration describe changing of velocity so the answer is constant acceleration
Acceleration is defined as the rate of change of velocity.
Acceleration = (Change in velocity) / time taken
Acceleration = (Final velocity - initial velocity) / time
As the object velocity changes by the same amount in each second, it means the acceleration is constant.

PLZ HELP WILGIVE BRAINIEST!Read the false statement.
Each atom within a specific element has the same number of neutrons, which determines its atomic number.
Reword the statement so it is true.
Each atom within a specific element has the same number of protons, which determines its atomic number. The correct statement.
This is inaccurate because the atomic number of an element is determined by the number of protons in the nucleus of its atoms, not by the number of neutrons.
Each atom within a specific element has the same number of protons, which determines its atomic number. The atomic number of an element is a fundamental property that defines the element and its place on the periodic table.
The number of protons in the nucleus of an atom of that element. Neutrons, do affect the atom's mass and stability but do not determine their atomic number.
The correct statement is Each atom within a specific element has the same number of protons, which determines its atomic number.

A person walks 5,000 cm per day. How many km does that person walk in a year?
Answer:
18.25 km
Explanation:
Convert 5,000 cm to km: 5,000 cm / 10000 = 0.05 km
That person walks 0.05 km per day.
You will get the answer by multiply 365 days (a year): 0.05 km x 365 = 18.25 km

diffrence between UFP&LFP
Answer:
In the formula, 'X' is the temperature value to be converted, 'UFP' is the upper fixed point and 'LFP' is the lower fixed point of the temperature scale
Explanation:
LFP means Lower fixed point and UFP means Upper fixed point. Explanation: There are different scales with different lower fixed point and upper fixed point to measure temperature but the distance between these scales is same in any table or scale considered.
what is the density of a 75 g block of wood measuring 12 cm x 8cm x 9cm
Answer:
density is equal to mass divided by volume (m/v)
volume: 12×8×9=864cm³
75÷864=0.09
Answer: 0.09g/cm³
Force = Mass x Acceleration
i. Mass as subject.
ii. Acceleration as subject.
Answer:
1) mass = force / acceleration
2) acceleration = force / mass
Explanation:
Part 1)
Force = Mass x Acceleration
Divide both sides by acceleration
force / acceleration = mass
mass = force / acceleration
Part 2)
Divide both sides by mass
force / mass = acceleration
acceleration = force / mass

Explanation:
difference between:
1.distance and displacement
2.centripetal froce and centrifugal force
3.speed and velocity
4.velocity and acceleration
Explanation:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.Centripetal force is the force REQUIRED for circular motion. Centrifugal force is the force that makes something flee from the center.Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity.A 10cm tall object is placed perpendicular to

How far will a car move if it starts from rest, reaches a final speed of 40 m/s, and accelerated at 2 m/s/s?
Answer:
800 m
Explanation:
Acceleration (a) = Velocity (v) / Time(t)
a = (v-u) /t
where, v = final speed
u = initial speed
2m/s² = (40m/s - 0m/s)/t
that is, from rest is no speed.
2m/s² = (40m/s) /t
t = (40m/s)/2m/s²
t = 20 s
hence, the car has accelerated for 20 s.
From,
Velocity (v) = Displacement (d) /time(t)
displacement is the distance the car has travelled.
40m/s = d/20s
d = 40m/s × 20s
d = 800 m
When is the pressure of the man on the ground more – lying position or standing
position? Explain.
Hi,
The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.
To the point, a man standing position on the ground had more pressure.
More is the area of contact, less is the pressure efforted.
Thank you...
