Hi there!

Since the object is being pulled at a constant velocity, the forces must be balanced.
Since there is no movement vertically, we must take into account the horizontal forces. We can also assume a positive acceleration to be in the direction of motion.
The acceleration and force due to gravity on an incline is:
a = gsinФ
F = MgsinФ
∑F = -MgsinФ + T
Since it is getting pulled at a constant velocity, ∑F = 0. So:
0 = -MgsinФ + T
MgsinФ = T
Solve for T by plugging in values. Let g = 10 m/s²
T = (120)(10)sin(27) ≈ 545 N
Answer:
(a) The convex mirror image, is always upright at all positions, while images formed by concave mirrors are always inverted when the object distance from the mirror is more than the mirrors focal length.
(b) An upright image is not seen for object at a distance from a concave mirror further than the focal length of the mirror, which is the spoon in the question
Therefore, the location of her eyes of approximately, 30 cm, from the mirror is more than the mirror's focal length

<span>2. An electric current in a conductor creates a magnetic field at all points in the surrounding region.
3. A permanent magnet creates a magnetic field at all points in the surrounding region.
4. A moving electric charge creates a magnetic field at all points in the surrounding region.</span>
Braking up to -8 meters per second squared is more risky than the other one.
<h3>What is inertia?</h3>
According to the definition of inertia, matter has the ability to remain at rest or to move uniformly in a single direction unless applied with an external force.
The ability of moving object to remain in moving uniformly in a single direction is called inertia of moving.
In this case, the car moving with certain velocity has inertia of moving. By certain applying brakes of more deceleration is more risky as it works opposite to the inertia of moving. Hence, braking up to -8 meters per second squared is more risky than breaking up to -3 meters per second squared.
As 8 meters per second squared acceleration or deceleration is larger compare to other; there may have no situation where it can be the opposite.
