a sports event, the car starts from rest, in 5.0 s its acceleration is 5.0 m/s2.
culate the distance travelled by car.
Answers
Answer:
62.5m
Explanation:
Given parameters:
Time = 5s
Acceleration = 5m/s²
Unknown:
Distance traveled by car = ?
Solution:
To solve this problem, we use one of the motion equations as given below:
S = ut + [tex]\frac{1}{2}[/tex] at²
S is the distance traveled
t is the time taken
u is the initial velocity = 0m/s
a is the acceleration
Now insert the parameters and solve;
S = (0 x 5) + ([tex]\frac{1}{2}[/tex] x 5 x 5²) = 62.5m

What is a main difference between a mixture and a pure substance?
illl give you 100 points!!!
A mixture is only a liquid, but a pure substance can be in any state.
A mixture looks the same throughout, but a pure substance does not.
A mixture can vary in composition, but a pure substance has a set composition.
A mixture can be made up of a single compound, but a pure substance cannot.
Answers
Answer:
C
Explanation:
A-false, mixtures can be solids too.
B-false, pure substances will have a constant appearance
C-true, a mixture has two or more composition, but the pure substance has a constant composition
D-false, mixtures have more than 1 compounds as I said before
A mixture can vary in composition, but a pure substance has a set composition. Thus, a pure substance is homogeneous always.
What is a mixture?A mixture is the combination of two or more individual components which are mixed physically or chemically. Mixtures can be homogenous or heterogenous.
A pure substance is a fixed composition containing its own particles only. For example, water, fruits, pure metals etc.Thus, pure substances are always homogeneous. In the case of mixtures, the composition is not definite.
Homogeneous mixtures appears to be one phase whereas, a heterogenous mixture shows phase separation. The components of a mixture can be separated physically.

Alex's Range = 3.20 - 0.90 = 2.30
Sanni's Range = 1.35 - 1.30 = 0.05
Chai's Range = 2.10 - 1.05 = 1.05
Jimmy's Range = 2.20 - 1.55 = 0.65

28. A student notices that when a weight is hung on a spring, the spring stretches. She decides to conduct an experiment to determine the relationship between the amount of weight
placed on a spring and the distance the spring stretches. She has five different weights: 25 9,50 9.75 9. 100 9, and 125 g. She selects a weight, hangs it on the spring, and
measures how far the spring stretches
What is the independent variable in this experiment?
length of unst etched spring
distance the spring stretches
weight hung from the spring
O temperature of the spring
Answers
Answer:
C). weight hung from the spring
Explanation:
An Independent variable is characterized as the variable that is controlled or manipulated by the experimenter in order to observe its change on the dependent variable.
In the given experiment, 'weight hung from the spring' is the independent variable as it is manipulated by the researcher in order to witness its impact on the dependent variable(how the spring stretches). It is the cause that causes an effect on the dependent variable. Any change in the former directly affects the latter. Thus, option C is the correct answer.

Answers
Answer:
speed
Explanation:
Change in velocity, not velocity, is used to calculate the average acceleration. Velocity is displacement over time.
Acceleration:
It is defined as the ratio of change in velocity to time. It is given by:
Acceleration= Change in velocity / time
a= u-v / t
where,
u= initial velocity
v= final velocity
t= time
Thus, we can conclude that a change in velocity is used to calculate average acceleration.

Cannon ball of mass 3.5kg is fired at a speed of 22m/s2
Answers
Answer:
77N
Explanation:
Since we are not told what to find, we can as well look for the net force acting on the ball.
According Newton's second law;
F = mass × acceleration
Given
Mass = 3.5kg
Acceleration = 22m/s²
Net force F = 3.5×22
F = 35/10×22
F = 7/2×22
F = 7×11
F =77N
Hence the magnitude of force required is 77N
