Answer
Can the wave travel between the Sun and Earth.
Explanation:
This would be due to the fact that mechanical waves alone require a medium to travel. Electromagnetic waves that are produced on the sun subsequently travel to Earth through the vacuum of outer space. ... Mechanical waves require a medium in order to transport their energy from one location to another.
Possible terminal voltages are 6 - 1.5 =4.5 V or 6+1.5 = 7.5 V.
Voltage is the pressure from an electrical circuit's power supply that pushes charged electrons (present-day) thru an undertaking loop, enabling them to do work that includes illuminating a light. In quick, voltage = stress, and it's far measured in volts (V).
There are styles of voltage, DC voltage, and AC voltage. The DC voltage (direct modern-day voltage) usually has the same polarity (positive or poor), which includes a battery. The AC voltage (alternating current voltage) alternates between nice and bad.
Voltage, electric-powered capacity difference, electric-powered stress, or electric-powered anxiety is the difference in electric-powered capacity among points, which is defined as the work needed in step with a unit of charge to move a take a look at a rate between the two factors.

The "generational change" approach to managing innovation assumes that innovation is a predictable process made up of a series of steps and that compressing the time ittakes to complete those steps can speed up innovation.

B = 18 m
Theta = 112o
<u>Solve</u>
By = 18*sin(112) = 16.68
Bx = 18*cos(112) = -6.74
The answer is D
Seven
theta = - 40o It's going clockwise. You just put the angle in your calculator as -40o
By = 15*sin(-40) = -9.64
Bx = 15*con(-40) = 11.48
Answer: A

I'm going to answer this one as it is written.
Fx = F * cos(37)
Fx = 20N * cos(37)
Fx = 15.87 N The answer is A.
Fy is not calculated for this because Fy pulls Rover up. He's not going to like that very much. You have to know this when you are walking your dog and you pull him up at an angle. Part of what you are doing is choking him for no good purpose. That's part of the physics of everyday living.
This is a case of linear expansion. The general expression of linear expansion is given by:
ΔL = αLΔT, ΔL = change in length or height, α = coefficient of linear thermal expansion, ΔT = Change in temperature.
In the current case;
α = 2.5*10^-6 /°C (for Marble)
L = 170 m at 30.0°C
ΔT = 30 - (-16) = 46°C
Substituting;
ΔL = 2.5*10^-6 *170*46 = 0.01955 m
Height at -16°C = 170 - 0.01955 = 169.98 m
