Answer: there can't be acceleration when there is no movement
Explanation:
Answer:
Explanation:
Maximum distance after which the motorist must have to stop is given as
now the distance after which the vehicle will stop on applying breaks is given as
now remaining distance is given as
now reaction time is given as
<u>The correct answer is 580.
</u>The upward force the right tension cord exerts on the traffic light is equal to about 114.35 N. Because the stoplight is being help upright the natural force (upward force) provided by both tension cords must be equal to the gravitational (downward) force of the traffic light which is 331.
If 114 is the upward force on the right side then 216 N must be the force provided by the left side.
You then have a right triangle with the length opposite theta = about 216 and theta = 22. So sin(22)* X = 216, where X is the length of the hypotenuse, or the force found in the left cord.
with sig figs added to the mix the answer is 580 N
I believe the answer is true to the E dgenuity physics course
Answer:
mass- the amount of matter in an object
balance- tool used to measure mass
scale- a tool used to measure weight
weight- the downward pull on an object due to gravity
The charge on the left sphere negatively charged.
<h3 /><h3>What is charge?</h3>
Due to the physical property of electric charge, charged material experiences a force when it is subjected to an electromagnetic field. You might be electrically positive or negative. While similar charges repel one another, opposite charges attract.
In order for the neutral metal sphere and negatively charged metal rod to have the same potential, some negative charge must flow from the rod to the sphere in order for them to both have negative charges.
The sum of the negative charges in them would be equal to the initial negative charge in the rod since the entire charge is preserved.
