Consider the following scenario. A car for which friction is NOT negligible accelerates from rest down a hill, running out of gasoline after a short distance. The driver lets the car coast farther down the hill, then up and over a small crest. He then coasts down that hill into a gas station, where he brakes to a stop and fills the tank with gasoline. Identify the forms of energy the car has,
Answers
Answer:
The answer is below
Explanation:
Gravitational Potential energy is the energy stored by an object as a result of its vertical position or height.
Kinetic energy is the energy an object possesses due to its motion.
The law of conservation of energy states that energy cannot be created or destroyed but can be transformed from one form to another.
As the car accelerates down the hill, there is a change in gravitational potential energy as a result of decrease in vertical height. Some of the gravitational potential energy would be changed into work done by friction while the rest would cause an increase in kinetic energy due to the car acceleration. Lastly, when the brake is applied to stop the car, the car would lose its kinetic energy.

a glass beaker has a mass of 50g. a liquid of density 1.8g/cm3 is poured into the beaker until it reaches the 200cm3 mark. calculate the total mass of the beaker and its contents
Answers
Answer:
total mass = 410 g
Explanation:
density = 1.8 g/cm³
volume = 200 cm³
density = mass / volume
mass (of liquid) = density x volume
= 1.8 x 200
= 360 g
total mass (beaker + liquid) = 50 + 360 = 410 g [Ans]

What is energy?
Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to ball in order to accelerate it. We must put in effort in order to apply a force. Following work, energy is transmitted to the item, which causes it to move at a new, constant speed. An ball will store energy as the result of its position is potential energy.

What is the potential energy of a spring that is compressed 0.75 m by a 25 kg block if the spring constant is 85 N/m?
24
34
87
797
Answers
Answer:
Potential energy of spring = 24 Joules.
Explanation:
Given the following data;
Spring constant = 85N/m
Extension, e = 0.75m
Mass = 25kg
To find the potential energy of a spring
Potential energy of a spring is given by the formula;
P.E = ½ke²
Substituting into the equation, we have
P.E = ½*85*0.75²
P.E = 42.5 * 0.5625
P.E = 23.91 ≈ 24 Joules
P.E = 24 Joules

Position 2 because North America is tilted towards the Sun
Position 3 because North America is parallel to the Sun
Position 4 because North America is tilted away from the Sun

It is winter in North America in position 4 because North America is tilted away from the Sun.
What is cycle of seasons of Earth?The "cycle of seasons" is caused by the occurrence of each season one after the other throughout the year. The seasons are also influenced by variations in the atmosphere, air vapour, wind, and precipitation.
A season other than summer and winter is created when rain falls continuously throughout a certain time. Other than summer and winter, seasons are seen to occur in different regions due to the local conditions.
As shown in the figure, at position 4, North America is tilted away the Sun, the sun light falls on America in tilted manner. Hence, It is winter in North America in position 4. Whereas at position 2, North America is tilted towards the Sun and It is summer in North America in position 2.

Answer:
the equations of motion can be separated into an equation that depends on a single variable.
Explanation:
he one-dimensional kinematics equations can be applied to two-dimensional systems because we can write the equations in such a way that each one of them depends on variables in a single dimension plus time, which, because it is a scalar, can be used in all dimensions.

Gravity Rocks!
Three friends were talking about gravity. One friend
held up a rock and asked his friends whether the gravi-
tational force on the rock depended on where the rock
was located. Each friend had a different idea about a
place where the gravitational force on the rock would
be the greatest. This is what they said:
Lorenzo: "I think if you put the rock on the top of a very tall mountain, the gravita-
tional force on the rock will be greatest."
Eliza: "I think the gravitational force will be greatest when the rock is resting on
the ground near sea level."
Flo: "I think you have to go really high up. If you drop the rock out of a high-
flying plane, the gravitational force will be greatest."
Explain why you agree with
Which friend do you most agree with?
that friend.
Answers
Answer:
Eliza’s suggestion is the most promising
Explanation:
Newton’s law of universal gravitation is [tex]F = G\frac{m_1m_2}{r^2}[/tex] where G is a constant and both masses are constant in this experiment as well. So it only depends on r, the distance between the center of mass of both objects.
Bringing it high in the sky, as Flo suggests, is definitely not a good idea because it only increases the distance from the center of the Earth mass.
A mountain contains significant mass, so the center of the Earth mass is somewhat shifted to regions with the largest mountains. However, standing on top of a mountain, as Lorenzo suggests, doesn’t help since the shift of the center of mass, if any, is far smaller than the height of the mountain.
Standing near sea level, as Eliza suggests, is a good way to minimize the distance to the center of the Earth mass.
A square metal plate of edge length 12 cm and negligible thickness has a total charge of 5.6 × 10-6 C. (a) Estimate the magnitude E of the electric field just off the center of the plate (at, say, a distance of 0.49 mm from the center) by assuming that the charge is spread uniformly over the two faces of the plate. (b) Estimate E at a distance of 29 m (large relative to the plate size) by assuming that the plate is a charged particle.
Answers
Answer:
a) 2.2*10^7 N/C
b) 60 N/C
Explanation:
To start with, we say that the
Area charge of the plate, σ = q/2A
σ = 5.6*10^-6 / 2(12*10^-2)²
σ = 5.6*10^-6 / 0.0288
σ = 1.944*10^-4 C²/m
Next, we find the electric field
Electric field, E = σ/Eo
Electric field, E = 1.944*10^-4 / 8.85*10^-12
Electric field, E = 2.2*10^7 N/C
b)
E = kq/r²
E = [8.99*10^9 * 5.6*10^-6] / 29²
E = 50344 / 841
E = 60 N/C
This means that the E at a distance of 29 m is 60 N/C
Over an interval of 4.0 s the average rate of change of the concentration of B was measured to be -0.0760 M/s. What is the final concentration of A at the end of this same interval if its concentration was initially 1.600 M?
Answers
Complete question:
Consider the hypothetical reaction 4A + 2B → C + 3D
Over an interval of 4.0 s the average rate of change of the concentration of B was measured to be -0.0760 M/s. What is the final concentration of A at the end of this same interval if its concentration was initially 1.600 M?
Answer:
the final concentration of A is 0.992 M.
Explanation:
Given;
time of reaction, t = 4.0 s
rate of change of the concentration of B = -0.0760 M/s
initial concentration of A = 1.600 M
⇒Determine the rate of change of the concentration of A.
From the given reaction: 4A + 2B → C + 3D
2 moles of B ---------------> 4 moles of A
-0.0760 M/s of B -----------> x
[tex]x = \frac{4(-0.076)}{2} \\\\x = -0.152 \ M/s[/tex]
⇒Determine the change in concentration of A after 4s;
ΔA = -0.152 M/s x 4s
ΔA = -0.608 M
⇒ Determine the final concentration of A after 4s
A = A₀ + ΔA
A = 1.6 M + (-0.608 M)
A = 1.6 M - 0.608 M
A = 0.992 M
Therefore, the final concentration of A is 0.992 M.

answer : The moment of inertial felt by someone ( J ) is greater that the moment of inertia felt by the motor i.e. J > Jm
Explanation:
Gear ratio G > 1

moment of inertia felt by Motor = moment of Inertia at the armature
b) Determine the moment of inertial felt by someone who is rotating the mass by hand
moment of inertia felt by someone is = J
