Hurricane are killing them
Given:
f = 1160 kHz = 1160 x 10³ Hz
The velocity is c = 3 x 10⁸ m/s, the velocity of light (approximmately).
Calculate the wavelength, λ.
c = fλ
λ = c/f = (3 x 10⁸ m/s)/(1160 x 10³ 1/s) = 258.62 m
Answer: 258.6 m
Choices 'A', 'C', and 'D' are off-base.
Here are some 'reasons' to put into the mish-mash:
-- third law of motion
-- action and reaction forces
-- conservation of momentum
The kinetic energy of an object is given by:
Kinetic energy = 1/2 * mass * velocity²
Therefore, if the velocity of an object is doubled, its kinetic energy will increase 4 times. We may verify this mathematically as:
New velocity = 8 m/s
K.E = 1/2 * 80 * 8²
K.E = 2,560 J
The new kinetic energy will be 2,560 Joules
Answer:
Yes it is a solid
Explanation:
It just has unusual properties.
Does it float when you drop it? then it is not a gas.
Does it pour into any container as water does? Then it is not a liquid.
So it's a solid.
And it can change it's shape
