Answer:
Explanation:
E₀ = 229.1 V/m
E = E₀ / √2 = 229.1 / 1.414 = 162 V/m
B = E / c ( c is velocity of em waves )
= 162 / (3 x 10⁸) = 54 x 10⁻⁸ T
rate of energy flow = ( E x B ) / μ₀
= 162 x 54 x 10⁻⁸ / 4π x 10⁻⁷
= 69.65 W per m².
Answer:
A.
Explanation:
It will stay in motion unless for example, someone stops it from going.
Answer:
On a velocity-time graph… slope is acceleration. the "y" intercept is the initial velocity. when two curves coincide, the two objects have the same velocity at that time.
The mass of the soil sample is 82g.
- The container has a mass of 15g.
- Let the mass of the soil be "x" g.
- The mass of the container and soil combined is 97g.
- container mass + soil mass = total mass
- 15g + x = 97g
- x = 97g-15g
- x = 82g
- The amount of matter that makes up a physical body is known as its mass. It serves as a gauge for the body's inertia.
- The amount of matter that makes up any item or body is the best way to define mass. Everything we see around us is made of mass.
- In physics, mass is the most fundamental characteristic of matter and one of the fundamental quantities. The amount of matter in a body is referred to as its mass. The kilogram is the kilogram, which is the SI unit of mass (kg).
