An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?
Answers
Given that,
distance = d = 1200m
velocity/speed = s = 50m/s
time = t
Also,
s = d/t
And,
t = d/s
t = 1200/50
t = 120/5
t = 24
Therefore, it takes 24s to travel.
Answer: Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.
Explanation:
An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?
Data:
d = 1200 m
V = 50 m/s
t = ?
The formula for uniform motion is:
V = d/tWhere
V = speedd = distancet = timeWe clear the formula for time t:
t = d/v
t = (1200 m)/(50 m/s)
t = 24 s
Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.
A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.
The work done on the box is [___] Nm, and the power is [___] Nm/s.
h e l p
Answers
Answer:
100 Nm and 25Nm/s.
Explanation:
Given the following data;
Force = 25N
Distance = 4m
Time = 5secs
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 25*4
Workdone = 100 Nm
To find the power consumed;
Power = workdone/time
Substituting into the equation, we have;
Power = 100/4
Power = 25Nm/s
The work done on the box is 100 Nm, and the power is 25 Nm/s.

Ana exerts a force of 20 N on a volleyball that has a mass of 0.15 kg. What is the force that the volleyball exerts on Ana?
0.15 N
20 N
19.85 N
20.15 N
Answers
Answer:
20 N
Explanation:
The question above is related to "Newton's Third Law of Motion." It states that every action is being opposed by a reaction of equal size but different direction.
The action force in the situation above is 20 N while the reaction force here is the one coming from the volleyball. So if the action force is 20 N then it's a common sense that the reaction force is also 20 N.
Thus, 20 N is the amount of force that the volleyball is exerting on Ana.
Answer:
the answer is 20 N

Every time the student performs this cross, all of the offspring are green. What does that mean? A. The gene for green and brown are equally expressed because half the beetle parents have a green phenotype and half the beetle parents have a brown phenotype. B. The gene for green color is dominant over the gene for brown because all the beetle offspring have a brown phenotype. C. The gene for brown color is dominant over the gene for green color because all of the beetle offspring have a brown genotype. D. The gene for green color is dominant over the gene for brown color because all the beetle offspring have a green phenotype.
Answers
Answer:
b
Explanation:
bbhbh
The genes for green color are dominant over the genes for brown color because all the beetle offspring have a green phenotype. Therefore, option (D) is correct.
What is phenotype?In biology, a phenotype can be described as the observable characteristics of an organism which is the result of the interaction of environmental factors and genes. These traits involve physical appearances and any traits that we can observe.
The phenotype includes its physiological, biochemical, as well as behavioral properties. Genotype is inherited from the parents while the phenotype can be affected by lifestyle and environmental factors. Environmental factors such as nutrition, temperature, humidity, and mental health of the organism.
For example, flamingoes are white in color but turn pink because of the pigments they need from their diet. Therefore, flamingoes portray how they are affected by environmental factors. The phenotype of an organism changes, accordingly to environmental factors.

an electric motor converts electrical energy into what kind of energy?
A) potential
B) kinetic
C) stored
D) chemical
Answers
Answer:
B.) Kinetic energy.
Explanation:
A better answer would be mechanical energy, but they do not have that up there.
An electric motor converts electrical energy into kinetic energy. The rotational kinetic energy of the motor is its mechanical energy to work.
What is energy transformation ?Energy can neither be created nor be destroyed. However, it can be transformed from one form to the other. Hence, the total energy of a system is conserved.
The energy lost in one form is equal to the energy gained in another form. We are using many electrical devices all are working under the process of energy transformation.
In an electric motor, the electrical energy is converted to the rotational kinetic energy of the motor. It is used for mechanical work of the motor. The rotational kinetic energy make the motor rotating. Hence, option B is correct.

Todd expends 400J while pushing a lawn mower across 20m. What force did he use to mow
the lawn? Show your work.
Answers
Answer:
F = 20 N
Explanation:
The work is said to be done when an object is acted upon by an external force. And as a result of this force the object is displaced by some distance. Hence, the formula for the work done is given as:
W = F*d
where,
W = Work Done = 400 J
F = Force Applied = ?
d = Distance Covered = 20 m
Therefore, using these values in equation, we get:
400 J = F(20 m)
F = 400 J/20 m
F = 20 N

Answers
Answer:
The energy changes
Explanation:
When an non-conservative force (for example friction, air resistance, applied force) does work on an object, the total mechanical energy (Ek+Ep) of that object changes. If positive work is done, then the object will gain energy. If negative work is done, then the object will lose energy.
