Answer:
OD. The wave diffracted as it passed through the opening in the barrier.
Explanation:
A progressive wave (i.e waves in motion) has the capacity to bend around an obstacle on its path. This is one of the general properties of waves called diffraction. Others are: reflection, refraction, interference. Note that only transverse waves undergo polarization.
Diffraction of waves is the ability of waves to bend around an obstacle on its path during progression.
Thus, the bending of the part of waves as it passes through the barrier implies that the wave diffracted as it passed through the opening in the barrier.
The frictional force exerted by the road on the car is 3000N
Given the mass of the car is 1000 kg , the velocity of the car is 20m/s
and the time is 6.6s
We need to find the frictional force exerted by the road on the car
We know that Force = mass * acceleration
Now here Mass is given but acceleration is not given
So, we will find acceleration by using the formula v = u+at
Where u = 0
v = 20m/s
a = ?
t = 6.6
Substitute the values in the formula We get
v = u+at
20 = 0+(a)(6.6)
20/6.6 = a
∴ a = 3.03 m/s^2
Rounding to nearest tenth is 3m/s^2
Hence the acceleration is 3m/s^2
Now substituting the value of acceleration in F = ma
Where m = mass
a = acceleration
F = 1000*3
∴ F = 3000N
Hence the frictional force exerted by the road on the car is 3000 N

In regard to career, both Patricia and Pharaoh are in a state of identity Moratorium. This state of identity crisis leads them to explore their identity and values. However, they haven't committed yet but they are experimenting, Patricia tried a a variety of entry-level classes, while Pharaoh researched many areas of study until he can decide.
identity Moratorium is characterized by low commitment
and high exploration.
Answer:
When forces on a object become unbalanced, the object moves.
Explanation:
Explanation:
Since the bottle of water was inside the refrigerator, it is cooler than the air outside the refrigerator.
There is water vapour in the air which gets cooled by the bottle and changes state from gas to liquid and settles on the bottle.
