Explanation:
When all Kinetic energy goes Into heating we can write
Q= mc × change in temperature
Q = 1/2 mv^2
1/ 2 mv^2 = mc × change in temperature
cancel out m because its in both sides
1/2 v^2 = c × change in temperature
1/ 2 × 8.5 ×8.5 = 4190 × x
x = 0.00862 °C
The energy an object has as a result of motion is known as kinetic energy.A force must be applied to an object in order to accelerate it.We must put in effort in order to apply a force.After the work is finished, energy is transferred to the item, which then moves at a new, constant speed.
How is kinetic energy determined?
Kinetic energy has the following formula: K.E. = 1/2 m v2, where m is the object's mass and v is its square velocity.The kinetic energy is measured in kilograms-meters squared per second squared if the mass is measured in kilograms and the velocity is measured in meters per second. A particle or an item that is in motion has a sort of energy called kinetic energy.An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force. When all Kinetic energy goes Into heating we can writeLet's consider a few instances where we see kinetic energy in daily life while keeping this formula in mind.Hydropower Plants, Windmills, Moving Cars, Gunshots, Flying Airplanes, Walking and Running, Cycling, and Rollercoasters are just a few examples.Q= mc × change in temperature
Q = 1/2 mv^2
1/ 2 mv^2 = mc × change in temperature
cancel out m because its in both sides
1/2 v^2 = c × change in temperature

BALANCED FORCES
When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . a stationary object stays still. ... a moving object continues to move at the same speed and in the same direction.

imagine that the Earth's rotation slowed down to one half of its original speed. What would life be like? Write a response that describes how your life would change. As always, write in complete sentences!
Explanation:
if you meant ¾ of it's original speed then a day would have 42 hours thus making days & nights longer. Our weight would be more, because as the Earth would rotate slower, it would exert less centrifugal force on us. There would also be a temperature change as each hemisphere (Eastern and Western) would get more time to warm up from the Sun's rays. the year would obviously have half the amount of days and week which would mess up our schedules as well as our holidays and lastly there'll be younger deaths.
A certain cubed object has a side of 76cm3 and a density of .76g/cm3, what is its mass? *
5776g
57.76g/cm3
100g
0.01
Mass = density x volume
Mass = 76 x 0.76 = 57.76
Answer: 57.76g/cm3
Answer:
5776
Explanation:
Obtain Center of Mass:
Obtain the center of mass of an axis of a thin wire with a curve defined by [tex]y=f(x)=x^{3/2}[/tex] from x=0 to x=1 and a lineal density of mass of [tex]p(x)=x^{2}[/tex]
Hi there!
To find the center of mass:
[tex]com = \frac{1}{m}\int\ {rdm}[/tex]
We can begin by changing "dm" into an available quantity by expressing the lineal density as a function:
[tex]\lambda = x^2 = \frac{m}{x}\\\\x^2 = \frac{m}{x}\\\\x^3 = m \\\\[/tex]
Differentiate both sides:
[tex]3x^2dx = dm[/tex]
Let:
[tex]r = f(x) = x^{3/2}[/tex]
Thus:
[tex]com = \frac{1}{m} \int x^{3/2}3x^2dx\\\\com = \frac{1}{m} \int }3x^{7/2}dx\\[/tex]
Evaluate:
[tex]com = \frac{1}{m} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right.[/tex]
We found 'm' above, so plug the expression in:
[tex]com = \frac{1}{x^3} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right. \\\\com = \frac{1}{x^3} \frac{2}{3}x^{9/2}\left \| {{1 \atop {0}} \right. \\\\com = \frac{2}{3}x^{3/2}\left \| {{1 \atop {0}} \right. = \boxed{\frac{2}{3}}[/tex]
Hello, I wanted an answer from a mathematician. The number 1.04 is closer to the number 1, 2, 1.25 or 1.5.
Answer:
1
Explanation:
line them up in order.
1, 1.04, 1.25, 1.5, 2
1.04 is in the middle of 1 and 1.25
1.04-1=0.04
1.25-1.04= 0.21
Answer:
1
Explanation:
1.04 lies between 1 and 1.25.
1.04 is 0.21 away from 1.25
1.04 is 0.04 away from 1.
0.04<0.21
A pulley system has an efficiency of 87.5 percent.
How much of the rope must be pulled in if a force of
648 N is needed to lift a 150 kg desk 2.46 m?
(Disregard friction.)
Answer:
work done on desk = m g h = 105 * 9.81 * 2.46 = 2534 Joules
Explanation:
so work in = 2534 / 0.875 = 2896 Joules
that is your 648 times distance your hand moved holding the rope
2896 = 648 * x
4.47 meters
I think maybe a typo, 648 N is too big, maybe 64.8 ? Any block and tackle system does better than that.

Imaging playing a game of baseball on the moon, which has less gravity than Earth and no atmosphere. How would you want to change the game to make it play fairly and fun?
Answer:
In order to reduce the mass of the bat and raise the mass of the ball, the transfer of momentum could only be extended to a distance equal to the size of a baseball stadium. Although the ball's acceleration stays constant regardless of its mass (provided that the mass is less than the mass of the moon), your running time around the bases will be reduced as a result of the increased mass of the ball.

Why would a train need more than one locomotive? Apply forces and net forces to explain what problems might be solved by adding locomotives to a train.
The more the number of locomotives in the train the greater the net force supplied to move the train forward.
A train is used for transportation on land. A train consists of a locomotive engine which provides the forward force which the train requires to move from place to place.
The more locomotives, the more power is provided to pull the train forward thereby providing a greater net force that moves the train in the forward direction.

The total momentum of a system of two moving identical bodies is zero. What should be true about the velocities of the bodies?
A) The velocities should be equal in direction and opposite in magnitude.
B) Both velocities should be zero
C) Both velocities should be equal in magnitude and opposite in direction
D) the velocities should be equal in magnitude and opposite in direction
For a zero total momentum of two bodies, the two velocities of the two bodies should be equal in magnitude and opposite in direction
According to the principle of conservation of linear momentum, the total momentum of an isolated system is constant.
[tex]Pi = P_f \\\\m_1u_1 + m_2u_2 = m_1v_1 + m_2 v_2[/tex]
where;
u is the initial velocity of the two bodiesv is the final velocity of the two bodiesm is the mass of the two bodiesWhen the total momentum is zero, the velocities of the two bodies will have equal values but opposite signs.
Thus, we can conclude that for a zero total momentum of the two bodies, the two velocities should be equal in magnitude and opposite in direction

One mole (6.02×10^23 atoms) of helium atoms in the gas phase has 3700 J of microscopic kinetic energy at room temperature. Assume that all atoms move with the same speed. The mass of a helium atom is 6.68×10^−27 kg. What is the speed of a helium atom?
This question involves the concepts of kinetic energy, and rms speed.
The rms speed of helium atom at 5800 K is "1.05 x 10¹⁵ m/s".
We will use the formula of the average kinetic energy of gas molecules to find out the rms speed of the hydrogen atom. rms speed is the root mean square speed of an atom:
[tex]K.E =\frac{1}{2}mv^2\\\\v=\sqrt{\frac{2K.E}{m}}[/tex]
where,
v =rms speed = ?
K.E = Kinetic Energy of Helium atoms = 3700 J
m = mass of hydrogen atom = 6.68 x 10⁻²⁷ kg
Therefore,
[tex]v=\sqrt{\frac{2(3700 J)}{6.68\ x\ 10^{-27}\ kg}}\\[/tex]
v = 1.05 x 10¹⁵ m/s

a car has a displacement of 480 kilometers to the east in 8 hours . What it’s the velocity per hour?
Answer:
The velocity is 60 km/hr.
Explanation:
Given:Displacement (d) = 480 km = 48000 m
Time (t) = 8 Hours = 480 minute
Velocity (v) = ?
Now,
Velocity = Displacement ÷ Time
v = d/t
v = 480/8
v = 60 km/hr
Thus, The velocity is 60 km/hr.
