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.

For any eclipse, all three bodies are in the same straight line. For a solar eclipse, the moon is the one in the middle. For a lunar eclipse, the Earth is the one in the middle.
White dwarf is white and dim
Answer:
Lowest resonant frequency:
Wave Speed:
Explanation:
The lowest resonant frequency
For a fixed string a resonant mode is always a integer multiple of fundamental frequency (the lowest resonant frequency):
Is the frequency for a resonant mode
is fundamental frequency (the lowest resonant frequency).
Due to problem says that there's not intermediate resonant frequencies between 684 Hz and 798 Hz, i.e, they are consecutive resonant modes, equations are as follows:
Solving for n from equation (1) and replacing it in the equation (2)
And finally solving for
Wave speed
For a fixed string the wave speed can be calculated by using
Where V is the wave speed and L is the string length.
So, using this equation and solving for V:
<em>It Is very important convert the string length unit to meters</em>
Answer:
6.708 × 10⁸ miles/h
Explanation:
Given:
Speed of Light = 3.00 × 10⁸ m/s
1 mile = 1610 m
⇒1 m = 1/1610 mile
also 1 second = 1/3600 hrs
so 3.00 × 10⁸ m/s = (3.00 × 10⁸ ×3600) / 1610 m/h = 6.708 × 10⁸ miles/h
thus 3.00 × 10⁸ m/s = 6.708 × 10⁸ miles/h
