Answer:
The train will have a greater impact than the bike
The train will have a bigger net force than the bike, so the acceleration of the train will be slower than the bike. In order to achieve the same acceleration, the train requires a bigger net force.
Answer:
Image result for State the general purpose of an experiment, using the terms dependent and independent variable
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable

Answer:
Length of cable = 16.7 m
Distance from ground = 15.4
New angle between pole and cable = 58.5 degrees
Explanation:
The flagpole forms a right-angled triangle with the cable and the ground.
Let the adjacent side be the flagpole, the hypotenuse be the cable and the ground be the opposite side.
hypotenuse = h
adjacent = 6.8 m
distance from ground = d
angle = 66.0
cos 66 = 6.8/h
h = 6.8/cos 66
h = 16.7 m
tan 66 = d /6.8
d = 6.8 * tan 66
d = 15.3 m
If the cable is brought 4.2 m closer to the pole, new distance = 15.3 - 4.2 = 11.1 m
let new angle be x
tan x = 11.1/6.8
x = tan⁻¹ (11.1/6.8)
x = 58.5 degrees
Complete Question
A parallel plate capacitor contains a positively charged plate on the left, and a negatively charged plate on the right. An electron in between the plates is moving to the right. Which statement is true?
Group of answer choices
a The potential energy of the electron is decreasing and it is moving to a region having a higher potential
b The potential energy of the electron is decreasing and it is moving to a region having a lower potential.
c The potential energy of the electron is increasing and it is moving to a region having a lower potential
d The potential energy of the electron is increasing and it is moving to a region having a higher potential.
Answer:
The correct option is C
Explanation:
From the question we are told that
An electron in between the plates is moving to the right
Generally the potential energy of the electron is mathematically represented as
Here e is the charge on the electron and V is the electric potential of the electron
Generally the left side with the positive charge has a higher potential than the right side with the negative charge
Now when the potential energy of the electron increases it will move toward the plate with the lower potential which is the left plate
Answer:
5N
Explanation:
Because if it moves to the right, that means F is weak and 6N is STRONK
