Answer:
3
Explanation:
v = v⁰ (its original speed) + a (negative acceleration) X t² (time)
v = 15 - 10 x 1.2 = 15 - 12 = 3 (it's slowing down)
Answer:
a = -2.82 m/s²
v = 18.4 m/s
Explanation:
Initial velocity, u = 26.0 m/s
Final velocity, v = 0 m/s
Distance travelled, s = 120m
Using
v² = u² + 2as
0 = 26² + 2(120)a
a= -2.82 m/s²
Velocity of the car when it was 60.0m past the point where the brakes were applied:
u = 26.0 m/s
a = -2.82 m/s²
s = 60m
Using
v² = u² + 2as
v² = 26² + 2(-2.82)(60)
v² = 337.6
v = 18.4 m/s
Answer: C. the rod gains mass and the fur loses mass.
Explanation:Atomic particles have mass. The electron has a mass that is approximately 1/1836 that of the proton and with exchange exchange of charge this is also factored in. The movement of effect described above is known as the triboelectic charging process—charging by friction—which results in a transfer of electrons between the two objects when they are rubbed together. Plastic having a much greater affinity for electrons than animal fur pulls electrons from the atoms of fur, leaving both objects with an imbalance of charge. The plastic rod would have an excess of electrons and the fur has a shortage of electrons. Having an excess of electrons, the plastic is charged negatively and has more mass. In the same vein, the shortage of electrons on the fur leaves it with a positive charge and consequently with lesser mass.
According to I.S. standards, the maximum deflection should typically not be greater than 1/325 of the span.

What is Beam deflection?</h3>
A beam is a long segment of a body that can support a weight while defying bending. Beam deflection is the term for the movement of a beam when a force is applied to it in a certain direction.
The beam has the ability to be bent or shifted from its initial position. The deflection is represented by this distance along each member point.
The amount of displacement that a certain structural member may experience with the aid of a sizable amount of load is known as deflection. It may also be known as the angle or the separation. The slope of the deflected form of the body under a load directly influences the distance of deflection of a member under that force.
