The car’s average velocity is mathematically given as

V=4m/s

Average velocity is simply the mean rate of change of position of a car over a period of different times and this can be used to attain velocity of a car that has been in different velocity states

Generally, the equation for the Velocity   is mathematically given as

V=(AI/OI)

Therefore

V=24/1

V=4m/s

In conclusion, the car’s average velocity

V=4m/s

Answer:

Through the testing of hypotheses.

Answer: One example of an experiment you can do is find out the heat difference between a white car and a black car using the sun in a hot day.

Explanation: The black car would absorb more heat from the sun and would make the inside of the black car hotter than the white car.

Answer:

a hypothesis is an assumption made before any research has been completed for the sake of testing (basically what you think is going to happen). A theory is an explanation for what has been shown many times. (what happened with evidence)

The minimum speed with which a projectile will travel a range is given by the speed when the given range is taken as the maximum range for the given speed

The minimum takeoff speed for such a leap is approximately 9.9 m/s

The known parameter is the distance a grey kangaroo can leap = 10 meters

The required information is the minimum takeoff speed for the leap

Solution:

The path of motion of the kangaroo as they leap is the path of a projectile

The distance of the leap is the range of the projectile

The formula for the maximum range is presented as follows;

[tex]Maximum \ range, R = \mathbf{ \dfrac{v_0^2 }{g}}[/tex]

v₀ = The initial speed of the kangaroo

g = The acceleration due to gravity ≈ 9.81 m/s²

The minimum speed to reach a maximum range of, R = 10 meters is found as follows;

[tex]\mathbf{ Maximum \ range, R} = 10 \, m = \dfrac{v_0^2 }{9.81 \ m/s^2}[/tex]

Therefore;

v₀² = 10 m × 9.81 m/s² = 98.1 m²/s²

v₀ = √(98.1 m²/s²) ≈ 9.9 m/s

The minimum takeoff speed for the kangaroo to leap 10 meters on horizontal ground, v₀ ≈ 9.9 m/s

Answer:

two protons and two neutrons

it's the answer. hope it helps

Alpha particles have two protons and two neutrons. Therefore, option (D) is correct.

Alpha particles can be defined as positively charged particles released from the decay of several radioactive materials. The mass of the Alpha particle is because of the presence of two protons and two neutrons. Therefore, the Alpha particles nucleus is very similar to the nucleus of the Helium atom and are denoted by the Greek alphabet α.

An alpha particle or ray is also known as doubly ionized helium nuclei (He²⁺). The alpha particle's mass is equal to 6.64 × 10⁻²⁷ Kg. Alpha particles are generally generated during the standard radioactive decay of atomic nuclei.

Alpha particles contains the kinetic energy of 5MeV and a speed of 5 % of that of the speed of light. They are also formed in high-energy particle accelerators and are highly ionized particles with low penetration depth compared to other particles.

Answer:

Option A - Sound waves must move through a substance

Explanation:

Unlike light waves, sound waves must travel through a medium/substance for such a medium to vibrate and then produce sound.

As a matter of fact sound can't travel through empty space.

Thus, looking at the options given, the correct one is:

Answer:

5.25m to 52.5 Decimeters (10x)

5.25m to 5250 Millimeters (1000x)

Answer:

E = q V B     describes the electric field induced

E Proportional to V B

while the magnet is pushed into the coil the induced field (B) will increase (consider 1 turn of the coil)

If V is constant the E-field will increase due to increasing B and the galvanometer will deflect accordingly

When V drops to zero the deflection must again be zero

So one would see a blip due to the deflection of the galvanometer

Note that as V increases the galvanometer will deflect one way and then as V drops to zero the deflection will be opposite (drop to zero when V is zero)

B always increases to a constant value because of the properties of the magnet.
