The speed and direction of an object's motion is its?
Answer:
Speed and direction of motion is velocity. ... A change in speed is a change in velocity – so, a change in speed is an example of acceleration!
Measure
Remember that velocity includes the speed and direction of an object. Therefore, a change in velocity can be either a change in how fast something is moving or a change in the direction it is moving.
The speed and direction of an object in motion is called velocity
How do i know what speed and direction is called?Speed is defined the distance traveled with time. Mathematically, it is expressed as:
Speed = distance / time
Direction of an object is simply the path of motion of an object.
Velocity of an object is defined as the displacement traveled with time i.e
Velocity = displacement / time
Displacement of an object is the distance in a specific direction.
Thus, we can say that the velocity of an object is the speed in a specific direction.
With the above information in mind, we can conclude that the speed and direction is called velocity.

Levi decides to examine the effect of fertilizer on the growth of tomato plants. He chooses four plants for his experiment and applies varying amounts of fertilizer to the three of them. He does not apply fertilizer to one plant.
Over a 15-day period, the plants receive fertilizer on Days 1, 4, 7, 10, and 13. Levi measures the height of all of his plants with a meter stick on Days 3, 6, 9, 12, and 15. He also makes sure to hold all experimental factors constant except for the fertilizer.
Which statement describes what Levi did to prepare the control group in his experiment?
Levi applied different amounts of fertilizer to three of his plants.
Levi did not apply any fertilizer to one of his plants..
Levi held all experimental factors constant except for fertilizer., ,
Levi measured his plants on five separate days.
Answer:
Levi did not apply any fertilizer to one of his plants..
Explanation:
In an experiment, there are two major groups namely: control group and experimental group. Control group is the group in an experiment that does not receive the experimental treatment i.e. the group which the independent variable is not applied to.
In this case, Levi is trying to examine the effect of fertilizer on the growth of tomato plants where he used varying amounts of fertilizer on three of the four plants he used for the experiment. The fourth plant did not receive any amount of fertilizer, which is the independent variable (variable being manipulated or changed). This means that Levi prepared the control group in his experiment by NOT APPLYING ANY FERTILIZER TO ONE OF HIS PLANTS.

How much kinetic energy does an 80 kg man have while running at 3 m/s?
Hello!
[tex]\large\boxed{KE = 360 J}[/tex]
Use the equation KE = 1/2mv² to solve for the kinetic energy of the man.
We are given the mass and velocity, so plug these values into the equation:
KE = 1/2(80)(3²)
KE = 1/2(720)
KE = 360 J
When a charge is released in an electric field, it moves from a point of potential
Explanation:
Protons/positive charges will move from higher potentials to lower potentials
While Electrons/Negative charges move from lower potentials to higher potential
Normally, electrons are negatively charged hence they tend to be repelled by the electrons and attracted by protons.
A jeep starts from the state of rest. If its velocity becomes 60 km/hr in 5 minutes, (i)
What is the acceleration of the jeep? (ii) What is the distance covered by the jeep?
Answer:
acceleration= velocity/time
60km/hr = 60 km /60 mins = 1km/min so accn = 1km/5= 1000m/5 = 200m/m
v²= u²+2as
(1000)² = 0²+ 2 x 200 x s
(1000)²/400= s
2500m

Compare venus's rotation to Earth's
Firstly its axis of rotation is inclined at 177.36 degrees (compared to 23.5 degrees on Earth). This means that Venus rotates in a retrograde direction from east to west, making the Sun rise in the west and set in the east. Further to this the rotation is very slow: a sidereal day on Venus lasts 243 Earth days.

What is the heat that is released into the atmosphere when energy is changed into mechanical energy called?
Answer:
thermal pollution
Explanation:
took exam!
When the heat is discharged into the atmosphere then energy is changed into mechanical energy is known as Thermal pollution.
What is Thermal pollution?
When Thermal pollution is the degradation of water differentia by any procedure that changes ambient water temperature.
A typical motivation for thermal pollution is the usefulness of water as a coolant by power plants and industrial manufacturers.
When the water utilized as a coolant is returned to the biological environment at a more elevated temperature, the sudden transformation in temperature lowers the oxygen supply and affects ecosystem composition.

It is safer for a car driver to be wearing a seat belt, compared with not wearing a seat belt, if the car is involved in a collision.
Explain why.
Explanation: It is because when a car is moving both the car and the driver is in inertia of motion. When a car is involved in collision it comes to a sudden stop and the car comes into inertia of rest whereas the person still in inertia of motion moves forward and might result in major injuries. But this can be prevented by wearing a seatbelt

D. In a circuit, voltage and power are unrelated.
C. Increasing the voltage in a circuit increases its power.
is the relationship between voltage and power in a circuit
How is voltage impacted by power?The watt is the unit of power measurement. The power will quadruple if the voltage increases. In a circuit, if the voltage (or electrical pressure) is raised, the current (flow of electrons) will rise in direct proportion; for example, doubling the voltage will result in doubling the current flow.
Several different voltages will produce the same amount of power as long as you can pull adequate current (amps) from the battery. Hence, hypothetically, a higher voltage does not automatically translate into more power. Typical voltage values for peak (max) volts are 40, 80, and 120 volts.

What is the current through the battery if the switch S is opened
Answer: So, our current when our switch is open is going to be equal to the voltage across the resistors, and that's going to be our 12 volts, 12 volts, divided by the equivalent resistance of these resistors. When the switch is open, essentially, we just have R1 and R2 in series, and so this is just gonna be R1+R2.

Answer:
The value of [tex]X = 1000 \ N[/tex] and [tex]Y = 1400 \ N[/tex]
Explanation:
Considering the diagram,
Taking moment about the pivot , we have
[tex]X * 1 = 400 * 2.5[/tex]
=> [tex]X = 1000 \ N[/tex]
Generally given that the bar is at equilibrium then the upward forces is equal to the down ward force
So
[tex]Y = X + 400[/tex]
=> [tex]Y = 1000 + 400[/tex]
=> [tex]Y = 1400 \ N[/tex]
