Answer:
4) Long exposure to low-energy radiation could give the same dose as a short burst of high-energy radiation.
Explanation:
When it comes to ionizing radiation, absorption should be kept as low as reasonably achievable (ALARA). This can be achieved by control of time spent in the vicinity of the source, the distance to the source and the use of personal protective equipment (PPE).
A short burst of high-energy radiation releases or generates a high radiation dose in a short time frame. This can also be achieved due to long exposure to low-energy radiation, which results into the gradual accumulation of the dose.

V = 1.50 x 3.00 / 1.00 = 4.50 L </span>
Sound waves can't travel through a vacuum.
The net force on the object is 5 N.
Explanation:
We can calculate the net force on the object by using Newton's second law of motion:
where
F is the net force on an object
m is the mass of the object
a is its acceleration
For the object in this problem, we have
m = 1 kg is its mass
is its acceleration
Substituting into the equation, we find the net force:
