Answer:When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.
Explanation:
Answer:
v = 34.35 m/s
Explanation:
In order to find the speed of the car, when it has traveled 60m, you take into account the Work-Energy theorem, which is given by the following formula:
(1)
W: work done on the roller coaster by the electromagnetic propulsion
m. mass of the roller coaster = 700kg
v2: final speed of the roller coaster = ?
v1: initial speed = 0m/s
you have that the force exerted on the roller depends on x, the distance traveled by the roller. To calculate the work W, you use the following integral:
(2)
where F is given by:
You replace the previous function F in the integral (2) and calculate W:
Next, you solve the equation (1) for v2, and replace the values of all parameters:
The final speed of roller coaster, after it has traveled 60m is 34.35m/s
C. it’s amplitude. any comments leave them
25 meters per second.
To find this, divided 150 by 6 in order to get the correct calculation.
Hope this helps!
Answer:
The charge is
Explanation:
From the question we are told that
The mass of each ball is
The distance of separation is
Generally the weight of the each ball is mathematically represented as
where g is the acceleration due to gravity with a value
substituting values
Generally the electrostatic force between this balls is mathematically represented as
given that the the charges are equal we have
So
Now from the question we are told to find the charge when the weight of one ball is equal to the electrostatic force
So we have
=>
