Question: Initially, the car travels along a straight road with a speed of 35 m/s. If the brakes are applied and the speed of the car is reduced to 13 m/s in 17 s, determine the constant deceleration of the car.
Answer:
1.29 m/s²
Explanation:
From the question,
a = (v-u)/t............................ Equation 1
Where a = deceleration of the car, v = final velocity of the car, u = initial velocity of the car, t = time.
Given: v = 13 m/s, u = 35 m/s, t = 17 s.
a = (13-35)/17
a = -22/17
a = -1.29 m/s²
Hence the deceleration of the car is 1.29 m/s²
Russian nesting dolls are an amazing comparison for the strongest magnet in the world, because the magnitis were inserted inside each other. The magnets would be adapted so they could be put together, Because they are closer, the coils of the magnet would be tougher. The magnets would be able to magnetize better.
Answer:
Electromagnetic induction is a phenomenon in which a changing magnetic field across a loop of wire results in the generation of an induced emf. When there is relative motion between a magnet and the coil, magnetic flux changes and hence an electromotive force is generated in the coil.
Answer:
The force on each wire is
Explanation:
From the question we are told that
The acceleration at which the elevator will stop is
The weight of each section of the wire is
Generally here are weight at each section
Generally considering the first section, the force acting along the y-axis is mathematically represented as
Here represents the tension on the wire at the first section while represents the weight of the lamp at the first section
So
=>
=>
=>
Generally considering the second section, the force acting along the y-axis is mathematically represented as
=>
=>
=>
=>
Generally considering the third section, the force acting along the y-axis is mathematically represented as
