Answer:
0.09 x10^-10m
Explanation:
Using wavelength=( 12.27 A)/√V
= 12.27 x 10^-10/ √1.6x10^2
= 0.09x10^-10m
68% So 68/100 of freshwater is found in ice
Answer:
10N to the left side towards you
Explanation:
The net force is the resultant force that acts on a body.
Force is a push or pull on a body.
Push to left side = 25N
Pull to the right = 15N
Net force = Push to left side - Pull to the right = 25N - 15N
Net force = 10N to the left side towards you
The net force is therefore 10N to the left side towards you
<u>Answer
</u>
He should make the arrow for “Path” curve downward.
<u>Explanation
</u>
The force of gravity is usually directly downward. So from the diagram, it is correctly labelled.
If the object was given a horizontal force, the direction of the inertial is also correct. Inertial is the force the resist the change of state of motion.
What Hector should change is the path followed by the object. It will be a curve not a straight line as it is drawn.
The correct answer is He should make the arrow for “Path” curve downward.
