Which property of an object changes when an unbalanced force acts on it?
Mass
Inertia
Velocity
Temperature
Answer:
Velocity
Explanation:
When unbalanced forces acts on an object the velocity of the object changes. This is because, unbalanced forces causes a body to accelerate.
Acceleration is the rate of change of velocity with time taken.
An unbalanced force on a body causes a net force greater than zero and this makes the velocity of the body to change.
Therefore, an unbalanced force on a body will cause a change in the velocity of the body.
Answer:
velocity
Explanation:
mhm
how do i calculate this?
CAR 1
Momentum = Mass/Velocity
M = 2100/20
M = 105 m/s^2
CAR 2
Momentum = Mass/Velocity
M = 2100/30
M = 70 m/s^2

One role of a producer in a food chain is to provide? A) water for plants B) sunlight for plants C) nutrients for animals D) shelter for animals
Answer:
Nutrients for animals
Explanation:
Producers are organisms that produce their food, they do not need to depend on other animals for their food. They possess photosynthetic properties that enable them to produce their food.
These set of organisms are located at the bottom of the food chain, they can convert components like water, sunlight and air into carbohydrate through the unique process of photosynthesis.
Without these producers, the food chain would not exist as they form the base and foundation of the food chain, some lower animals depend on them as their source of food.

A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration?
plz, show the equation.
Answer:
6m/s²
Explanation:
Given parameters:
Initial velocity = 4m/s
Time = 3s
Final velocity = 22m/s
Unknown:
Average acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time taken.
Acceleration = [tex]\frac{Final velocity - Initial velocity }{Time}[/tex]
Acceleration = [tex]\frac{22 - 4}{3}[/tex] = 6m/s²

1134000J
Use the formula for kinetic energy K= 1/2*m*v^2

Explanation:
The car transports 180 m in 12 s. Calculate its speed and express it in m / s and in km / h
Explanation:
Given parameters:
Distance = 180m
Time = 12s
Unknown:
Speed in m/s and km/hr
Solution:
Speed is the distance divided by the time taken,
Speed = [tex]\frac{distance}{time}[/tex]
So;
Speed = [tex]\frac{180}{12}[/tex] = 15m/s
1000m = 1km
3600s = 1hr
Therefore;
15 x m x [tex]\frac{1}{s}[/tex] x [tex]\frac{1km}{1000m}[/tex] x [tex]\frac{3600s}{1hr}[/tex] = 54km/hr

What is the charge of a Sulfur atom if it has 17 electrons?
Answer:
-1
Explanation:
An atom contains a proton, electron and neutron as subatomic particles. The number of protons, which is the positively charged particle (+) is always equal to the number of electrons, which is the negatively charged particle (-) in A NEUTRALLY CHARGED ATOM i.e. no charge.
However, a decrease or increase in charge is dependent on the number of electrons and protons in that atom. Sulfur atom has an electron number of 16 in its neutral atom, however, when it gains one more electron to become 17, it means that the charge has become -1 because the charge = number of protons - number of electrons i.e. 16 - 17 = -1.

A student fires a cannonball diagonally
from the ground as shown. Neglect drag
and the initial height of the cannonball.
After the ball lands on the ground enter
zero for all speeds and heights if necessary.
Answer:The cannons total flight time is 2.23seconds
Explanation:
A ball fired diagonally is fired at an angle of 45° to the horizontal. The motion of the fired ball is a projectile motion. A projectile is a motion in which an object fired into space with an initial velocity U is allowed to fall freely under the influence of gravitational force.
To total time of flight T of the cannon ball can be expressed as;
T = 2Usin(theta)/g where;
U is the initial velocity or speed of the ball = 31m/s
theta is the angle that the ball make with the horizontal = 45°
g is the acceleration due to gravity = 9.81m/s²
Substituting the given datas into the formula we have;
T = 31sin45°/9.81
T = 31×0.7071/9.81
T = 21.92/9.81
T = 2.23seconds

A 5 kg block is pulled across a table by a horizontal force of 40 N with a frictional force of 8 N opposing the motion. Calculate the acceleration of the object.
Answer:
a = 6.4 [m/s²]
Explanation:
To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.
∑F = m*a
where:
∑F = sum of forces (horizontal force = 40 [N] and friction force = 8 [N])
m = mass of the block = 5 [kg]
a = acceleration [m/s²]
Now replacing:
[tex]40-8=5*a\\32 = 5*a\\a=6.4[m/s^{2} ][/tex]
Note: the sign of the friction force is negative since this force is acting against the movement of the block.
How do speed, velocity, and acceleration relate to objects in motion?
Answer:
However, it is important to remember that acceleration is change in velocity. So, even if an object is moving at a constant speed, if it changes direction, the object is accelerating. Most people think of acceleration as an increase in speed. However, slowing down is also considered acceleration.
