answer could differ since it's rolling down a ramp. if an angle is given our approach differs.
Answer:
Explanation:
Answer: Gamma rays
Gamma rays have the highest frequency.
What is an electromagnetic wave?
An electromagnetic wave requires no medium for its propagation.
It consists of a spectrum of different wavelengths.
Different wavelengths of rays have different energies and different frequencies.
Higher frequency rays have the highest energies.
What is gamma-ray?
These are ionized radiations.
Gamma radiations are obtained from the decay of the atomic nucleus.
It has the highest frequency which is why it can penetrate through matter.
It has the smallest wavelength and highest energy.
The frequency of gamma rays is more than 10^19 cycles per second and wavelength less than 100 picometers.
Where are the factors ... to this question
Answer:
(a) Melting point is 136.8°C
(b) Melting point is 278.24°F
Boiling point is 832.28°F
(c) Melting point is 409.8K
Boiling point is 717.6K
Explanation:
(a) 586.1°F = 5/9(586.1 - 32)°C = 307.8°C
Melting point = 444.6°C - 307.8°C = 136.8°C
(b) Melting point = 136.8°C = (9/5×136.8) + 32 = 278.24°F
Boiling point = 444.6°C = (9/5×444.6) + 32 = 832.28°F
(c) Melting point = 136.8°C = 136.8 + 273 = 409.8K
Boiling point = 444.6°C = 444.6 + 273 = 717.6K
A = delta v over delta t delta v is calculated with final velocity less initial velocity then delta v is equals to 20 - 0 that is 20m/s and to calculate delta t is like delta v is final time less initial time as initial time always is 0 the delta t is equals to 10s then a = 20/10 then acceleration is 10m/s^2 (remember that is squared)
