Answer:
Explanation:
At the lowest point velocity is zero
loss of potential energy = gain of spring energy
= mgh = 1/2 k h² , h is vertical downward displacement , k is spring constant
2 mg = k h
h = 2mg / k
= (2 x .2 x 9.8) / 50
= .0784 m
P E ( gravitational) = - mgh
= - .2 x 9.8 x .0784
= - .1536 J
spring PE = + .1536 J
Total PE = 0
b )
At mid point ie at h = .0392 m
gravitational PE = .2 X 9.8 X .0392
= - .0768 J
Elastic PE = 1/2 X 50 X .0392² = .0384 J
Total = - .0768 J + .0384 J
= - .0384 J
At mid point total energy = 0
- .0384 + KE = 0
KE = .0384 J
c )
1/2 m v ² = .0384
v² = 2 x .0384 / .2
= .384
v = .6196 m / s
62 cm / s
0.74in
Explanation:
Given parameters:
length range of adult mosquito = 3.0 - 6.0mm
Smallest mosquito = 2.5mm
Largest mosquito = 19mm
Average mass range = 3.0 - 5.0mg
Unknown:
Length of largest known mosquito in inches = ?
Solution;
The length is the longest dimension. It is how long a body is.
The problem here is converting from mm to inches;
The length of the longest mosquito which is the largest is 19mm
19mm to inches;
1mm = 0.039inches
19mm = 19mm x
= 0.74in

Answer:

Explanation:
*Assume the parallel disks have equal diameters.
Given the electric strength as
transferring
electrons, the disk's Area can be calculated using the formula:

#We now calculate the disks diameter:

Hence, the diameter of the disks is
