(1,24) (0,0)
Please find the attached photograph for your answer. Hope it helps! Please do comment
The car’s average velocity is mathematically given as
V=4m/s
What is average velocity?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
What is the car’s average velocity?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

hope it is helpful for you keep smilingIf the magnet is now pushed into the coil and then held stationary inside the coil describe fully what would you observe on the galvaromoter?
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.
What is the difference between a hypothesis and a theory?
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)
Explanation:
The distance between Earth and the Moon was determined by measuring the time it took for light waves from Earth to travel to the Moon and back. Why was it not possible to use sound waves for this experiment? A Sound waves must move through a substance. B Sound waves would change frequency on the return to Earth. C Sound waves move too slowly for the technique to be accurate. D Sound waves move more slowly in Earth’s atmosphere than in space I NEED HELP ASAP
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:
Sound waves must move through a substance which is Option A

a grey kangaroo can lead a distance of 10m on horizontal ground. what is the minimum takeoff speed for such a leap?
show your work please!!
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

Alpha particles have two protons and two neutrons. Therefore, option (D) is correct.
What is an alpha particle?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.
