what is the kinetic energy of an object with a mass of 80 kg and velocity of 12 m/s east?
Answer:
KE = 1296 J
Explanation:
tony walks at an average speed of 70 m/min from his home to his school.If the distance between his home and the school is 2100 , how much time does it take for tony to walk to school
It takes 30 minutes for Tony to get to school.
2100 divided by 70 is 30, which would represent the amount of minutes.
Also he is walking very fast to be getting 70 in a minute.
Hope this helps and have a nice day.

How does density affect refraction?
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from the air through a diamond.
Answer:
The density of a material affects the speed that a wave will be transmitted through it. In general, the denser the transparent material, the more slowly light travels through it.

An empty container has a mass of 3 g. When it is filled with 5 cm3 of a liquid,
the total mass of container and liquid is 7 g. What is the density of the liquid, in g/cm3?
Answer:
THE MASS OF THE LIQUID IS 22.5 g
Explanation:
Density = 0.180 g/cm3
Side length = 5 cm
Mass = unknown
To calculate the mass of the liquid, we use the formula:
Mass = density * volume
Volume of a cube or cuboid container = l^3
Volume = 5 ^3 = 125 cm3
So therefore, the mass of the liquid is:
Mass = 0.180 * 125
Mass = 22.5 g
In conclusion, the mass of the liquid in the container is 22.5 g

Answer:
frequency = 5 /s
period = 0.5 s/
Explanation:
number of revolution = 10+10/2 = 20/2 = 10
frequency = n/t = 10/5 = 5 /s
period = t/n = 5/10 = 0.5s
The can-chiller decreases the temperature of the liquid in the can by 15 °C.
The mass of liquid is 0.33 kg.
The specific heat capacity of the liquid is 4200 J / kg °C.
Calculate the energy transferred from the liquid as it cools.
Answer:
Energy transferred, Q = 20790 J
Explanation:
Given that,
The change in temperature of the liquid, [tex]\Delta T = 15^{\circ} C[/tex]
The mass of liquid, m = 0.33 kg
The specific heat capacity of the liquid is 4200 J/kg°C.
We need to find the energy transferred from the liquid as it cools. The energy transferred is given by :
[tex]Q=mc\Delta T\\\\Q=0.33\times 4200 \times 15\\\\Q=20790\ J[/tex]
So, 20790 J of energy is transferred from the liquid as it cools.

Answer:
The force of the bat is pushing harder than the ball. When there are unbalanced forces, one will move less or more than the other. Balanced forces stay the same force, that's why they're call "balanced" forces. so in this example, the bat has a stronger force than the ball, which causes the ball to have a greater reaction

Two masses oscillating together with each of their time period as ,'T'
To find↷New time period ,'T'Answer↷Option B
Time period is independent of mass so it will remain same irrespective of the mass on the spring so the new time period would be the exact same as the previous one.Solution↷we know that,
The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :
[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]
m⇢mass of the body [kg]k⇢spring constant [Nm^-1]According to the question,
The new mass would be 2mThe new spring constant would be 2kso,
The new time period would be
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]
[tex] \huge \rightarrow \: T ' \: = T[/tex]

Scenario:The owner of Bond's Gym wants your advice. He asks you if you think positive incentives would work better than negative incentives.He is considering these options: - Raising or lowering prices - Applying discounts or fees - Offering exclusive memberships Bond's Gym should use to help solve the problem. If the owner of Bond's Gym raises his prices, the demand for membership will most likely . If the owner of Bond's Gym decides to raise his prices, he could make money per monthly membership.
Answer: Negative Incentives
Decrease
More
Explanation:
Took it on EDG 2021
Price can be defined as the amount of money that must be paid by a buyer (customer) to a seller (producer or owner), so as to acquire goods and services.
This ultimately implies that, it is an amount of money a customer that is buying goods and services are willing to pay to the seller (producer or owner) for the goods and services being offered.
In this scenario, we can deduce the following points:
If the prices of Bond's Gym services are raised, the demand for membership will most likely decrease.If the prices of Bond's Gym services are raised, the owner could make more money per monthly membership.Read more on price here: https://brainly.com/question/11898489
With respect to 2D projectile motion, which of the following statements is true?
Answer:
The correct answers are
The following statements are true about an object in two-dimensional projectile motion with no air resistance
D) The speed of the object is zero at its highest point.
E) The horizontal acceleration is always zero and the vertical acceleration is always a non-zero constant downward
Explanation:
A) The speed of the object is constant but its velocity is not constant.
False the vertical velocity increases on descent
B) The acceleration of the object is constant but its object is + g when the object is rising and -g when it is falling.
False, the acceleration is -g when the object is rising
C) The acceleration of the object is zero at its highest point.
False, the acceleration is constant in magnitude throughout the motion
D) The speed of the object is zero at its highest point.
True, the direction of motion changes at the highest point from hence the body comes to rest and the speed is zero
E) The horizontal acceleration is always zero and the vertical acceleration is always a non-zero constant downward
True, the horizontal acceleration has associated force during motion but the vertical acceleration is due to gravity which is constant downwards

A 2.0-kilogram mass is moving with a speed of 3.0 m/s. What is the kinetic energy of the mass?
Answer: 9 Joules
Explanation:
Kinetic enegry is one half the mass multiplied by the velocity squared
KE = 1/2mv^2
[tex]KE=1/2(2)(3^2)\\KE=3^2\\KE=9J[/tex]
The kinetic energy of the body is 9J
What is kinetic energy?Kinetic energy is the energy possessed by a body due to its motion.
It is claculated by formula,
K.E = [tex]\frac{1}{2}mv^{2}[/tex]
Here,
The mass of the body = 2.0kg
speed = 3.0m/s
So kinetic energy K.E = [tex]\frac{1}{2}mv^{2}[/tex]
K.E = [tex]\frac{1}{2} (2)3^{2}[/tex] = 9J
So the kinetic energy of the body is 9J

What is the size of the force acting on a copper wire with a magnetic flux density of 3.6 x 10 2 T acting at
right angles to the wire of length 19 m and current of 0.043 A? Round your answer to 2 significant
figures.
Answer:
2900 N
Explanation:
We are given;
Magnetic flux density; B = 3.6 × 10² T
Length of wire; L = 19 m
Current; I = 0.043 A
Formula for force in this regards is;
F = BIL
Where;
B is Magnetic flux density
I is current
L is length
Thus;
F = 3.6 × 10² × 0.043 × 19
F = 2941.2
To 2 significant figures gives;
F = 2900 N

How does air outside the cup affect the knetic energy of the particles in the wall and the cold water
Answer:
Air outside the cup affect the kinetic energy of the particles in the wall and the cold water by transferring its heat to the cup and cold water.
Explanation:
The air outside the cup has a high temperature as compared to that of the cold water with in the cup.
As this hot and moist air it comes in contact of cup, it transfers its heat energy and become cool itself thereby leaving water droplet on the outer side of the cup.
Due to heat imparted to the cup, the atoms with in the cup and cold water starts vibrating and hence there kinetic energy increase.
