Answer:
Wave speed, frequency and wavelength in refraction
Explanation:
The diagram shows that as a wave travels into a denser medium, such as water, it slows down and the wavelength decreases. Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. Hope this helps :>
Energy = mc (delta T) where m is the mass in kg, c is the specific heat capacity, and delta T is the change in temperature.
450 = (45x10^-3)c (78-22)
450 = (0.045)c (56)
c = 178.57 J/kgK
How Maria can correct her error is by changing the fourth point to "applies to accelerating objects.". Option D. This is further explained below.
<h3>What is einstein’s special theory of relativity?</h3>

Answer:
320m/s
Explanation:
Step 1: State your values
s= NOT NEEDED
u=20m/s
v=?
a=10m/s²
t=30 seconds
Step 2: Find a suitable suvat equation:
v=u+at
Step 3:
subsitute values into equation:
?=20+(10x30)
20+300
320m/s
Usually, you have to take two years of physical sciences with lab. It doesn't have to be physics, it can be chemistry or biology.
