When does the object have potential energy?
Answer:
To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position.
Explanation:
An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Please help I’ll mark brainlyest
Answer:
10N right
Explanation:
The 10N of force acting down and up on the object cancel out.
The 15N of force pulling the force to the right is stronger than the 5N of force pulling the object left
15N - 5N = 10N
The magnitude and unit is 10N, and the direction is right
although the pivot exerts a force on the ruler it does not exert a torque with respect to the pivot point. why not?
Answer:
The situation is not shown, however if one calculates torques about the pivot point, then the pivot point itself exerts no torque because the force applied by the pivot point exerts zero torque because Fp * L = 0 where L = 0 in this case.
If one wants to calculate torques about, say, the end of the ruler then one would need to calculate the torque applied by the pivot point.

A box of mass 4kg is being pulled along a rough surface to the right, as shown below. When F=8N, the box accelerates to the right 1m/s^2. If F is doubled to 16N, the acceleration of the box across the same rough surface will be:
A) 1m/s^2
B) 2 m/s^2
C) 3 m/s^2
D) 4 m/s^2
E) 0.5 m/s^2
Hi there!
Recall that:
∑F = ma
In the given situation, there is acceleration occurring in the horizontal direction, so there is a net force.
∑F = Fa (Force applied) - Fκ (Force due to kinetic friction)
We can plug in given values to solve for the frictional force:
ma = Fa - Fκ
(4)(1) = 8 - Fκ
4 = 8 - Fk
Fκ= 4N (negative since working opposite to acceleration)
Now, solve given the new force:
4a = 16 - 4
4a = 12
a = 3 m/s², Answer C.

If you increase the elasticity of a material, what happens to the speed of a mechanical wave going through it?
Answer:
At the molecular level, materials are held together by bonds, which act like springs for small displacements from the equilibrium spacing between neighboring atoms. Push the atoms close, the bond pushes back to keep them apart. Pull them apart, the bond pulls the atoms closer. For those small displacements, it acts like a spring
The speed of the wave will be related to the stiffness of of those springs - you compress the material - how quickly do all of those little springs rebound and push their neighboring atoms away, sending that wave of compression through the material.
Explanation:
22. Calculate the displacement in meters a cyclist would travel in 5.00 h at an average
of 12.0 km/h to the south west
A 63 kg boy and sled are pulled along level ground with a force of 577 N. The boy and sled
are moving at a constant velocity of 2.4 m/s. What is the size of the frictional force?
Answer:
The size of the frictional force is 577 N.
Explanation:
What is frictional force?Frictional forces are exerted every time you have two surfaces sliding across one another. Friction depends on:
how rougher are the surfaces on contact;how harder you push one surface to the other.There are two types of friction:
static friction [tex]f_s[/tex];dynamic (sliding) friction [tex]f_d[/tex].Now let's attack the problem:
First, you have to write the data down:
[tex]\bullet \quad m= 63\,kg\\\\\bullet \quad F= 577\,N\\\\\bullet \quad v= 2.4\,m/s[/tex]
If the boy and the sled moves on constant velocity, Newton's First Law Of Motion states that the net force acting on them must be zero:
[tex]F_{net}=0[/tex]
Applying Newton's Second Law Of Motion, we get:
[tex]F-f_d=0[/tex]
which means that:
[tex]F=f_d[/tex]
In other words, the dynamic frictional force equals the force that moves the boy and sled. So we may write:
[tex]\boxed{f_d=577\,N}[/tex]
Conclusion: the size of the (dynamic) frictional force is 577 N.

what is a concentration?
Answer/Explanation:
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.
A concentration refers to a subject or study within a specific major. As part of the degree coursework, concentration classes count toward your major requirements as well.
MY PAPER IS DUE IN AN HOUR!!!
Your challenge- Write a paper on how to build, construct, and engineer a faster roller coaster. You essay must contain 5 paragraphs minimum. Each paragraph must be 3 sentences minimum.
Potential energy, Kinetic energy, Thermal energy and friction, speed, velocity, and acceleration, and the law of conservation of energy must be the main ideas of your paragraphs
Answer:
Your kinetic energy is always proportional to the square of your speed,
no matter whether you're on a bicycle, a roller coaster, or a baby carriage.
The faster you're moving, the more kinetic energy you have.
Your potential energy doesn't depend on speed at all, only on height.
On a roller coaster, the minimum speeds are usually at the top of a hill
or a loop, so the potential energy would generally correspond to the
slowest speeds. But again, that's not because of the speed. It's because
of the height.

A cheetah running initially at a velocity of 20 m/s accelerates
uniformly at 3.0 m/s. The velocity of the cheetah will be
m/s after 4.0 seconds.
Answer: I think it’s 32 m/s
Explanation: Vi=20 m/s
Vf=?
a=3.0 m/s^2
t= 4s
Vf= Vi + at
Vf= 20 m/s + (3 m/s^2)(4s)
Vf= 20 m/s + 12m/s
Vf= 32m/s
If A cheetah running initially at a velocity of 20 m/s accelerates
uniformly at 3.0 m/s2. The velocity of the cheetah after 4.0 seconds will be 32 m/s.
To find the velocity of the cheetah after some time we can use the formula:
v = u + at
where:
v = final velocity
u = initial velocity
a = acceleration
t = time
Given:
Initial velocity (u) = 20 m/s
Acceleration (a) = 3.0 m/s²
Time (t) = 4.0 seconds
now we can put values in eq.
v = 20 m/s + (3.0 m/s²) * 4.0 s
v = 20 m/s + 12 m/s
v = 32 m/s
so the answer is 32 m/s.
