Answer:
Part a)
k = 588.6 N/m
Part b)
v = 0.7 m/s
Explanation:
As we know that initially block is at rest
now if block is released from rest then it will go down by 10 cm and again comes to rest
so here we have
Part a)
Work done by gravity + work done by spring force = change in kinetic energy
Part b)
Now when spring is stretch by x = 5 cm then the speed of the block is given as
here we have
Answer:
As we can see, a string is attached with block A, and three string is folded with ply which is attached with B
x
B
=3x
A
Now differentiate with respect to x
V
B
=3V
A
Given,
V
A
=0.6m/s(totheright)
So,
V
B
=0.6×3
=1.8m/s(downward)
Explanation:
IF THE ANSWER IS RIGHT PLZ GIVE ME BRAINLIEST
THANK U
HAVE FUN AND BE SAFE
The most probably answer among the presented options would be the one that says "road map is to passenger".
Let us establish first that we do not know what a thesis statement means and that we are just taking the statement as it is without any prior knowledge to the hard word present. The key to this would be the statement "it lets her know where the writer will take her." Among the ones presented as options, only the road map fits the description. Thus, the answer being road map is to passenger. The car is subject to the driver's commands thus the driver is the one guiding the car, and the student follows what is written in the study guide.
Answer: OLEDs
Explanation:
The nanotechnology uses the surface of the carbon materials to generate the electricity. The evaporation of water on the surface of carbon materials helps in generation of electrical energy due to generation of thermal energy.
OLEDs can be defined as solid-state devices that comprises of organic molecules like carbon that will create electricity by exposing a surface for generation of thermal energy.
Answer:
100 m/s
Explanation:
here we use the wave equation which states that the velocity is equal to the product of the frequency and the wavelength.
so v = 50 × 2
v = 100 m/s
