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.

The most common states of awareness include conscious and unconscious. Wakefulness refers to a state of consciousness that is characterized by high levels of awareness and thought.
- Fast, irregular, and low-amplitude electrical activity correspond to WAKEFULNESS.
- An electroencephalogram is a diagnostic test that can be used to measure the brain's electrical activity during wakefulness and sleep.
- Wakefulness is characterized by low-voltage (i.e., 5 to 10 microvolts) and high-frequency brain waves. These waves are known as beta and gamma waves.
- Conversely, sleep is characterized by higher voltage and slow brain waves (i.e., synchronized pattern).

Answer: 0.137 m
Explanation:
Given
Mass of brick, m = 3 kg
Angle of inclination, Φ = 34°
Force constant of the spring, k = 120 N/m
The force of the brick, F can be gotten using the relation
F = mg
F = 3 * 9.8
F = 29.4 N
Now, the force parallel to the incline, F(p) can be gotten using the formula,
F(p) = F sinΦ, so that
F(p) = 29.4 * sin 34
F(p) = 29.4 * 0.559
F(p) = 16.4 N
The stretch distance then is,
d = F(p) / k * 1 m
d = 16.4 / 120
d = 0.137 m
Thus, the spring stretched by a distance of 0.137 m
Answer:
46 m and 159 m
Explanation:
first find initial x and y component of velocity and take final y component of velocity as zero at maximum point and follow steps as i have solved
Acceleration is -7 m/s²
Explanation:
initial velocity (u) = 14 m/s
since it's gonna stop,
final velocity (v) = 0m/s
time taken(t) = 2 seconds
now,
a = (v-u)/t
or, a = (0-14)/2
or, a = -14/2
a = -7m/s²
