Answer:
the coefficient of Kinetic friction between the tires and road is 0.38
Option A) .38 is the correct answer
Explanation:
Given that;
final velocity v = 0
initial velocity u = 15m/s
time taken t = 4 s
acceleration a = ?
from the equation of motion
v = u + at
we substitute
0 = 15 + a × 4
acceleration a = -15/4 = - 3.75 m/s²
the negative sign tells us that its a deacceleration so the sign can be ignored.
Deacceleration due to friction a = μ × g
we substitute
3.75 = μ × 9.8
μ = 3.75 / 9.8 = 0.3826 ≈ 0.38
Therefore the coefficient of Kinetic friction between the tires and road is 0.38
Option A) .38 is the correct answer
Answer: A
Explanation:
Isotopes of different elements differ by the number of neutrons inside the nucleus.
Answer:
1. enhance learning and memory ability in nonhuman organisms.
Explanation:
Genetic engineering can be defined as the process by which scientists modify the genome of an organism using new molecular tools. The resulting organism after the modification is known as Genetically Modified Organisms (GMO).
To create this genetically modified organisms requires recombinant DNA.
Advances in genetic engineering show that it is possible to enhance learning and memory ability in nonhuman organisms through biotechnology.
Answer:
572.85 v
Explanation:
V = IR
V = 100.5 * 5.7 = 572.85 v
Answer:
Explanation:
Here the rope is 10m long and making an angle of θ with the direction of canal or direction of flow of water in the canal .
sinθ = 2 / 10 = .2
θ = 11.5⁰
a )
Component of 500 N along the line perpendicular to the canal
= 500 sinθ
= 500 sin 11.5
= 100 N
b )
component of 500 N along the canal
= 500 cos 11.5
= 490 N approx .
