Answer:
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
I am pretty sure that the molecule that has an unbalanced arrangement of charge is placed in the second option from the scale represented above - Nitrogen gas (a diatomic molecule, N2). This one looks the only proper. I hope you will agree with me. Regards!
Answer:
6 s
Explanation:
First of all, we calculate the acceleration of the car in the initial situation, using the equation
where
v = 30 is the final velocity of the car
u = 0 is the initial velocity
t = 12 s is the time taken
Substituting,
So, this is the acceleration of the car.
In the second situation, the car velocity goes from
u = 0
to
v = 15 m/s
So, we can use again the same equation to find t, the time it takes for the velocity of the car to change between these values:
Answer:
Net force.
Explanation:
All of the forces acting on an object combine to create a net force.
Pressure is the force per unit area. This means that the pressure a solid object exerts on another solid surface is its weight in newton’s divided by its area in square metres
