Answer:
Electrical to kinetic
Explanation:
Answer:
Electrical energy is supplied to the blender.
Explanation:
This is converted into kinetic energy to turn the blades that blend the food, so energy is transferred from electrical to kinetic.
This is the useful energy change that we most want to happen.

A worker does 196 J of work to lift a bag 2m. What is the mass of the bag?
Work = 196 J = 196 kg.m^2.s^-2
[We know that 1J = 1 kg.m^2.s^-2]
Displacement = 2m
Acceleration (g) = 9.8ms^-2
We know that,
W=Fs and F=ma
So, W = (ma)s
=> W = m×a×s
=> 196 kg.m^2.s^-2 = m×9.8ms^-2×2m
=> 196 kg.m^2.s^-2 = m×19.6m^2.s^-2
=> 196 kg.m^2.s^-2 = m×19.6m^2.s^-2
=> (196 kg.m^2.s^-2)/(19.6m^2.s^-2) = m
=> 10kg = m
So, mass = 10kg

An airplane went from 120 m/s to 180 m/s in 4.0 seconds. What was its acceleration?
45 m/s2
15 m/s2
60 m/s2
30 m/s2
Answer:
15 m/s^2 The first thing to calculate is the difference between the final and initial velocities. So 180 m/s - 120 m/s = 60 m/s So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving 60 m/s / 4.0 s = 15.0 m/s^2 Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2

How much power does an Ox pulling a plow 20 m cross a field, exerting 120J of work over a period of 15 s?
Answer:
8W
Explanation:
Given parameters:
Distance covered = 20m
Work done = 120J
Time = 15s
Unknown:
How much power does the Ox exerts = ?
Solution:
Power is the rate at which work is being done
Power = [tex]\frac{Work done }{time}[/tex]
Power exerted by ox = [tex]\frac{120}{15}[/tex] = 8W

A 1.5 kg ball is thrown at 10 m/s. What is the ball's momentum?
Answer:
[tex]\boxed {\boxed {\sf 15 \ kg*m/s}}[/tex]
Explanation:
Momentum is the product of mass and velocity.
[tex]p=m*v[/tex]
The mass of the ball is 1.5 kilograms and the velocity is 10 meters per second.
[tex]m= 1.5 \ kg \\v= 10 \ m/s[/tex]
Substitute the values into the formula.
[tex]p= 1.5 \ kg* 10 \ m/s[/tex]
Multiply.
[tex]p=15 \ kg*m/s[/tex]
The momentum of the ball is 15 kilogram meters per second.
Answer:
15 kg m/s
Explanation:
[tex]p = mv \: = 1.5 \times 10 = 15 \: kgm {s}^{ - 1} [/tex]
Which of the following is NOT true about the relationship between electricity and magnetism?

How much work is done on a small car if a 1000 N force is exerted to move it 75
Answer:
75000J
Explanation:
Given parameters:
Force applied on the car = 1000N
Distance moved = 75m
Unknown:
Work done = ?
Solution:
The work done by a body is the force applied to move it through a particular distance.
So;
Work done = Force x distance
Therefore;
Work done = 1000 x 75 = 75000J

The diagram below shows a sled moving along a smooth, frictionless track.
Section 1
Section 2
Section 4
Section 3
In which sections of the track will the sled experience an unbalanced force?
A Sections 1 and 3
B Sections 2 and 3
C Sections 2 and 4
D Sections 3 and 4
Answer:
C. 2 and 4
Explanation:
my teacher went over it and the answer was that
The sections of the track in which the sled would experience an unbalanced force are: C. Sections 2 and 4.
The two types of force.In Science, there are two (2) main types of force that acts on an object and these include:
Balanced forceUnbalanced forceWhat is an unbalanced force?An unbalanced force refers to a type of force that occurs when two (2) or more forces acting on an object are unequal in magnitude, and as such, it typically results in a change of motion.
In this scenario, the sections of the track in which the sled would experience an unbalanced force are sections 2 and 4 respectively.

The potential energy of a watermelon is 15.0 J. The watermelon is 3.0 m high. What is the mass of the watermelon?
g = 9.8 m/s2
Answer:
m = 0.51[kg]
Explanation:
Potential energy is defined as the product of mass by gravity by height.
[tex]E_{pot}=m*g*h[/tex]
where:
Epot = potential energy = 15 [J]
m = mass [kg]
g = gravity acceleration = 9.8 [m/s²]
h = elevation = 3 [m]
Now replacing:
[tex]E_{pot}=m*g*h\\15=m*9.8*3\\m = 0.51[kg][/tex]

How does the magnitude of the force depend on the magnitude (absolute value) of charge 1 and charge 2.
Answer:
Product
Explanation:
The force between two charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex] ...(1)
Where
k is electrostatic constant
q₁ and q₂ are charges
r is the distance between charges
From equation (1), it is clear that the magnitude of the force is directly proportional to the product of charges.

what force acts between earth and the moon
Explanation:
Gravity
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
Juan rides his horse with a constant
speed of 18 km/h. How far can he travel
in 1/2 hour?
Answer:
He traveled 9km
Explanation:
To do this problem you need to use the equation which is Speed= distance/time and this problem gives you the speed which is 18 km/h and it gives you the time 1/2 hour so you write the equation 18= d/ 1/2 which his distance is 9km

Jimmy is cooking pasta in a pot of water on the stove. He uses a stopwatch to see how long the pasta takes to cook depending on the temperature of the water in the pot. What is the independent variable and why?
Answer:
stove
Explanation:
The stove is the independent variable in this question as it does not depend on anything like other variables such as pot, water, temperature and of cause pasta.
The pot depends on the stove, the water depends on the pot and stove, the pasta depends on the water and its temperature.
