Answer:
Commensalism
Explanation:
Commensalism is one example of the behavior of a goby and shark.
To work out kinetic energy, we use the following formula: KE = 0.5 x mv^2. So, 0.5 x 4 x 16^2 = 512 J
Answer:
D
Explanation:
At the other end of the spectrum toward red, the wavelengths are longer and have lower energy.
The product of mass and velocity is momentum. P=mv. The 'P' in the equation stands for momentum.
Answer:
A. Tends to get shorter.
Explanation:
When a constant current is sent through a helical coil, then currents are different turns will be equal as well as in the same direction. As currents in same direction attract each other, hence coil tends to get shorter.
