Answer:
Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles.
the giving off of rays of energy or particles by the breaking apart of atoms of certain elements (as uranium) 2 : the rays or particles that are given off when atoms break apart.
The three most common types of radiation are alpha particles, beta particles, and gamma rays.

<span>the sun raises the temperatures of molecules inside the balloon. As the molecules receives more kinetic energy, they move apart from each other and expand in volume. Depend on the balloon's material, it might not be strong enough to handle the pressure exerted by the gas inside, and the balloon will pop.</span>
Answer:0.8 meter
Explanation:
Frequency=426.7hz
Velocity=346m/s
Length =velocity ➗ frequency
Length=346 ➗ 426.7
Length =0.8
Answer:
4m/s2
Explanation:
The following data were obtained from the question:
U (initial velocity) = 10m/s
V (final velocity) = 30m/s
t (time) = 5secs
a (acceleration) =?
Acceleration is the rate of change of velocity with time. It is represented mathematically as:
a = (V - U)/t
Now, with this equation i.e
a = (V - U)/t, we can calculate the acceleration of the race car as follow:
a = (V - U)/t
a = (30 - 10)/5
a = 20/5
a = 4m/s2
Therefore, the acceleration of the race car is 4m/s2
Answer:
two dimensional to the motion means motion that takes place into different directions or coordinators at the same time the simplest motion would be an object moving liner in one dimension and example of liner movement would be car moving along a state rod and ball thrown straight from the ground
