Correct question:
Manny walked a total of 3 miles. The reference point used to calculate the total distance that he walked was the same as the ending point. Which describes where Manny most likely walked?
a. from the bottom of a hill to the top
b. on a circular nature trail
c. on a sidewalk from his house to the mall
d. from the beginning of a straight track to the end
Answer:
b. on a circular nature trail
Explanation:
As it is mentioned that Manny that his reference point from where she started is same as ending point meaning that she moved in a circular path making point B correct answer.
Answer:
Exothermic reaction
Explanation:
Exothermic reaction relases energy while endothermic absorbs energy.
When all parts of a circuit ... all the way from one terminal of the
battery or power supply to the other terminal ... are composed of
conducting materials, then current can flow in the circuit, and the
circuit is said to be 'closed'.
Work is done when spring is extended or compressed. Elastic potential energy is stored in the spring. Provided inelastic deformation has not happened, the work done is equal to the elastic potential energy stored.
Given that,
Deacelectration = -15 m/s²
Negative sign shows the declaration
Slowly speed = 25 m/s
Acceleration = 35 m/s²
Speed = 170 m/s
We need to calculate the time
Using equation of motion
Where, v = final velocity
u = initial velocity
a = acceleration
t = time
Put the value into the formula
We need to calculate the distance from the original runway
Using equation of motion
Hence, The distance from the original runway is 48.2 m.
