If two forces "balance" each other, that means that they add up to zero.
THAT means that they must have exactly equal magnitudes and exactly opposite directions.
If you want to draw a picture of a pair of two balanced force vectors . . . .
1). Draw two arrows with exactly the same length.
2). Flip one of them over, so that it points in exactly the opposite direction compared to the first one.
3). Place them tail-to-tail.
Head restraints are energy-absorbing device that protects against such injuries.
Head restraints are a car protection characteristic, connected or included into the pinnacle of each seat to restrict the rearward motion of the grownup occupant's head, relative to the torso, in a collision to save you or mitigate whiplash or damage to the cervical vertebrae.
Powerful head restraints are designed to reduce the rearward motion of the head in a rear-end crash and reduce the probability of occupants maintaining whiplash neck injuries. Head restraints are generally known as head rests.
Make certain the top of the top restraint is at least a degree from the pinnacle of your head. The role is the pinnacle restraint so it's as near the again of your head as possible. You may need to alter the again of seat.

<h3>What is called a circular?</h3>
A circular is just a letter with important information that is widely distributed. If, for example, you need to change the workplace's dress code or invite a whole department to a conference, a circular will be the most effective form of communication. Since the original intent of a leaflet or newspaper supplement was for it to circulate—to spread among a group of people—it is referred to as a "circular.
When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.
Let the mass of the satellite before explosion = 5M.
According to the conservation of movement
The velocity of the satellite before the explosion.
= velocity of M mean.
= velocity of 4M mean.
Since, =0 (A.C.Q)
The velocity of larger piece=.

Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion.

Answer: 0.666 V
Explanation:
Given
Radius of the loop, r = 14.8 cm = 0.148 m
Magnetic field present, B = 0.814 T
Rate of shrinking, dr/dt = 88.4 cm/s = 0.884 m/s
emf = dΦ/dt , where Φ = BA
emf = d(BA)/dt, where A = πr²
emf = d(Bπr²)/dt
if B is constant, then
emf = Bπ d(r²)/dt, on differentiating, we have,
emf = Bπ * 2r dr/dt
emf = 2πrB dr/dt, now if we substitute the values, we have
emf = 2 * 3.142 * 0.148 * 0.814 * 0.884
emf = 6.284 * 0.106
emf = 0.666 V
