Answer:
Explanation:
yes object can move through a distance and can have zero displacement
as displacement is the shortest distance between two points eg: if a person has moved a distance of 20 m and comes back to his original place by moving back 20m in such a case distance moved by the person is 40m but his displacement is 0 as shortest distance covered by him is 0 as he is in his original place
Yes, it is possible for a body to have traveled a distance yet have a displacement of zero.
Distance traveled by a body is the length of the path covered by it.
On the other hand displacement of a body is the shortest distance between the initial and the final point of a body.
When a body is traveling such that it ends at the point from where it started its journey, it covers a distance but the displacement of the body is zero.
So a body that has moved through a distance can have zero displacement.
Two parallel coils separated by a distance equal to the radius of the coils are known as Helmholtz coils. They are frequently used because they generate a magnetic field that is uniform over an appreciable region about its midpoint.

Answer:
#See details below.
Explanation:
-An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave.
-They produce continuous, repeated, alternating waveform without any input.
-Oscillators convert <em>unidirectional </em> direct current (DC) from a power supply to an alternating current (AC) signal of the desired frequency as determined by the circuit components.
False. When a chemical reaction occurs, atoms don't create or destroy. They are rearranged as bonds and are broken and formed together.
1. Answer:
The relationship between Force A and Force B is given as:
A = B
Explanation:
To produce acceleration to a body, an unbalanced force must be applied. Meaning that a Force must be applied to the body greater than that of Force of Friction.
In our case, a Force A is exerted on the crate which is moving with a constant velocity. As there is no acceleration, the force applied must be equal to the force of Friction B.
2. Answer:
The electron's acceleration is 1.756 x 10¹⁷ ms⁻².
Explanation:
Electric field exerts a Force on the electron given as:
F = 1.6 x 10⁻¹³ N
Rest mass of electron = 9.11 x 10⁻³¹ kg
According to newton's 2nd law of motion, a net force F applied on the electron must produce an acceleration 'a' which is directly proportional to the Force and inversely proportional to the rest mass of the electron given as:
a = F/m
a = (1.6 x 10⁻¹³)/(9.11 x 10⁻³¹)
a = 1.756 x 10¹⁷ ms⁻²
