Answer:

[tex]\boxed {\boxed {\sf A. \ 1000 \ Joules}}[/tex]

Explanation:

Kinetic energy can be found using the following formula.

[tex]E_k=\frac{1}{2}mv^2[/tex]

where m is the mass and v is the velocity.

The mass of the toy plane is 20 kilograms and the velocity is 10 meters per second.

[tex]m= 20 \ kg \\v= 10 \ m/s \\[/tex]

Substitute the values into the formula.

[tex]E_k=\frac{1}{2}(20 \ kg) (10 \ m/s)^2[/tex]

Solve the exponent first.

[tex]E_k=\frac{1}{2} (20 \ kg) (100 \ m^2/s^2)[/tex]

Multiply the last two numbers together.

[tex]E_k= \frac{1}{2}(2000 \ kg*m^2/s^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]E_k= 1000 \ kg*m^2/s^2[/tex]

[tex]E_k= 1000 \ J[/tex]

The kinetic energy of the toy plane is 1000 Joules

[tex]\large\boxed{38.34 m/s}[/tex]

Use the following kinematic equation to solve:

[tex]v_{f}^{2} = v_{i}^{2} + 2ad[/tex]

Where:

vf = final velocity (?)

vi = initial velocity (0 m/s, object started at rest)

a = acceleration (gravity = 9.8 m/s)

d = distance travelled (75 m)

Plug in the given values into the equation:

[tex]v_{f}^{2} = 0^{2} + 2(9.8)(75)[/tex]

Simplify:

[tex]v_{f}^{2} = 2(9.8)(75)\\\\v_{f}^{2} = 1470[/tex]

Take the square root of both sides:

[tex]v_{f} = \sqrt{1470} = 38.34 m/s[/tex]

Answer:

The temperatures

Explanation:

Heat rises

Answer:

30 N

Explanation:

Since the car travels at a steady speed of 20m/s and has a driving force of 30N, there is no net acceleration and thus, the resistive force is also 30 N in magnitude but in the opposite direction to the driving force. This is shown below.

F - f = f' where F = driving force = 30 N. f = resistive force and f'= net force.

f' = 0 since there is no acceleration. So,

F - f = 0

F = f = 30 N

The right answer is "30 N"

Answer explanation:

If a car is travelling at a steady speed, the resultant force must be zero, so the driving force and resistive force must be equal and opposite.

Explanation:

If you've ever heard of lake effect snow that is when cold air mass moves across long expanses of warmer lake water. The lower layer of air, heated up by the lake water, picks up water vapor from the lake and rises up through the colder air above; the vapor then freezes and is deposited on the leeward (downwind) shore. this is most common with lake Michigan when cold air travels down from Canada making the neighboring states colder, so YES, being near any body of water can effect the climate.

Answer: The pattern of the battery is wrong, the bulb is broken , the wires of the circuit is broken , the switch is not closed .

Answer:

circle the open switch on the right (it is open so the circuit is broken), the break in the wire on the left, opposite the switch (wire is broken so the circuit cannot continue) and on the left side of the bulb (bulb isn't fully connected so the circuit cannot continue). i think this is correct but my explanations may be a bit off, so just see where this takes you. hope it helps.

5 sets

Explanation:

Matches are played best of five sets. The first four sets are played to 25 points, with the final set being played to 15 points. A team must win a set by two points. There is no ceiling, so a set continues until one of the teams gains a two-point advantage. Previously, all sets were to 15 points, with the first four sets having a ceiling of 17 and the final set requiring at least a two-point winning advantage.

Answer:

231000kgm/s

Explanation:

Given parameters:

Mass of train car = 16500kg

Constant speed  = 14m/s

Unknown:

Momentum of the car  = ?

Solution:

To solve this problem, we must understand that the momentum of a body is the quantity of motion a body possess.

So;

 Momentum   =  mass x velocity

 Momentum  = 16500 x 14  = 231000kgm/s

Answer:

Net external force is the sum of all of the forcing acting on an object. Just because there are forces acting on an object doesn't necessarily mean that there is a net external force; forces that are equal in magnitude but acting in opposite directions can cancel one another out.

Explanation:

Answer:

Kk so your answers are: 1 is The sum of all the forces acting on an object is the net force or resultant force. If all the forces cancel out, the resultant force is zero, else, the unbalanced force will cause acceleration of the object. Force is a vector and hence has both a direction and magnitude. 2 is Depending on the magnitude and direction of the force, it can cause an object to move, stop or change direction. For example, in baseball a pitcher throws the ball with a certain speed towards the hitter, who hits it, thus applying a force to it.  and 3 is friction.

Answer:

145854.24J

Explanation:

Given parameters:

Specific heat capacity of water = 4.184J/g°C

Mass of the water  = 700g

Initial temperature  = 25.6°C

Final temperature = 75.4°C

Unknown:

Thermal energy  = ?

Solution:

To solve this problem, we use the expression below;

 H  = m x c x Ф

H is quantity of heat

m is the mass

c is the specific heat capacity

Ф is the temperature change

  H  = 700 x 4.184 x (75.4 - 25.6)  = 145854.24J

Answer:

4000 turns

Explanation:

The formula to apply is ;

Voltage in secondary coil/ Voltage in primary coil = Turns on secondary coil/Turns in primary coil

Vs/Vp =Ns/Np

Given that;

Ns=200

Vp=380 V

Vs=19 V

Applying the formula as;

Vs/Vp = Ns/Np

19/380 = 200/Np

1/20 =200/Np

Np = 200/0.05

Np= 4000 turns

Answer:

The normal line divides the angle between the incident ray and the reflected ray into two equal angles. ... The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection

The law of reflection is the idea that when light rays strike a smooth surface, the angle of incidence and the angle of reflection are both identical. Additionally, the incident ray, the reflected ray, and the surface normal all reside in the same plane.

Reflection of light refers to the act of light rays hitting a surface and reflecting back.

The law of reflection explains how both curved and planar mirrors form images.

Answer:

Objects in orbit around the Earth (like a satellite) still have net forces acting on them. True; An object with no net forces acting on it would not have a change in velocity. ... Therefore, there must be a net force acting on it.

Explanation:

Objects  in orbit around the Earth (like satellites) still have net forces acting on them. This is true, because this net force make change in their motion.

Force is an external force acting on object to change its state of motion or rest or to deform it. There are various kinds of forces such as gravitational force, magnetic force, nuclear force etc. Force is a vector quantity having both magnitude and direction.

The net force acting on a body depends on the direction and magnitude of all the forces acting on the object. The force acting on the objects that are orbiting around earth includes the gravitational force by earth, as well the force by other nearby planets or spatial objects etc.

Not all these force gets balanced and a net force always be there acting on these objects make them undergo changes in their state of motion.
