Become farther apart sense ice is more dense and not as easy to travel through as water.
The block on the table will move towards the right when the given unbalanced force act on the object. Option C is correct.
<h2>
</h2><h2>
Unbalanced Force:</h2>
When the force acting on the object is not equalized by the opposite force.
<h3>Net force: </h3>
It is defined as the vector sum of all forces acting on the object at an instance.
Where,
- net force
- Force acting on the right = 10 N
- Force acting towards left = -8 N
Put the values in the formula,
Since the net force is positive it means the move towards the right.
Therefore, the block on the table will move towards the right when the given unbalanced force act on the object.

Answer:
The thickness of the film is
Explanation:
The relation between the refraction index, and a wavelength is given by
<em>where is the number of fringes, is the wavelength of the incident light, and is the thickness of the film</em>.
<u>From this relation</u>, we have that
wich gives us that
is the thickness of the film.
Answer:
156.24N
Explanation:
From the data above;
Mass = 23g = 0.023kg
V = 88m/s
Kinetic energy = ½mv²
K.e = ½* 0.023 * 88²
K.E = 89.056J
The force required to accelerate the arrow to that speed and energy in 0.57m
Using equation of motion;
V² = U² + 2as
But U =0
V² = 2as
a = v²/2s
a = 88² / (2*0.57)
a = 6792.98m/s²
The force (F) that accelerates the arrow with that velocity = ?
F = M*a
F = 0.023 * 6792.98
F = 156.24N
