Since Sal drew the electron dot diagram of an aluminum atom, Sal should;
C. He should add a single dot below the symbol.
Nuclear energy is the stored potential energy in the nucleus of an atom. This form of energy is released either when unstable nucleus splits into smaller nuclei , known as fission, or when nuclei fuse together, a process known as fusion. Compared to this, light energy is a form of electromagnetic radiation such that it is composed of photons, which are small packets of light energy. Each photon has a characteristic wavelength, frequency, etc. Light energy has photons which have no mass whereas nuclear energy comes from nucleus, and involves mass.
Answer:
Mutations do not necessarily always have to be bad, sometimes plants or animals mutate with something helpful to the situation they are in.
Answer: After one hour the distance will be 64 800 meters, after 1 minutes the distance will be 1080m, after 1 sec the distance will be 18m.
Explanation: Distance is speed multiplied by the time taken.
Using the standard formula V= d/t
Where v is a velocity,
D is a distance and
t is time.
We get use the formula to multiply the time taken by the velocity.
Answer:
θ = 33°
Explanation:
Here, we can use the formula for the total time of flight of a projectile to calculate the launch angle of frog:
where,
θ = launch angle = ?
T = Total time of flight = 0.6 s
g = acceleration due to gravity = 9.81 m/s²
u = launch speed = 5.4 m/s
Therefore,
<u>θ = 33°</u>
