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.
The three physical forms are:
Solid, liquid, or gas.
Answer:
150J
Explanation:
Formula : <u>Work</u><u> </u><u>done</u>
Force x distance
work done = force x distance
Distance should be measured in meters
300÷100=3m
work done = 450 x 3
=150J
<h2>Answer: Any new and abnormal growth</h2>
A <u>neoplasm</u> is any <u>uncontrolled growth</u> of abnormal cells or tissues in the body.
This abnormal mass can be benign or malignant (carcinogenic).
Therefore, the correct option is D.
A) use v=u+at for both
First section, v=27, u=0, a=2.4. You should get 11seconds.
Second section, v=0, u=27, a=-1.3. You should get 21seconds.
This means that the total time is 22seconds.
b) You can either use s=ut+0.5at^2 or v^2=u^2+2as. Personally, I would use the second one as you are not relying on your previous answer.
First section, v=27, u=0, a=2.4. You should get 152m.
Second section, v=0, u=27, a=-1.3. You should get 280m.
This makes your overall displacement 432m.
