Newton’s second law of motion is force equals mass times acceleration.
F = m•a
An example of this would be hitting a ball. If you hit the ball, it will move however fast you hit the ball. The harder you hit the ball, the faster it will move.
hope this helps and brainliest please
The answer is above but I don't know if it's correct.
Answer:
Vmax=11.53 m/s
Explanation:
from conservation of energy
Spring potential energy =potential energy due to elevation
0.5*k*x²= mg
=mgh
0.5*k*2.3²= 430*9.81*6
k=9568.92 N/m
For safety reason
k"=1.13 *k= 1.13*9568.92
k"=10812.88 N/m
agsin from conservation of energy
spring potential energy=change in kinetic energy
0.5*k"*x²=0.5*m*
10812.88 *2.3²=430*
=11.53 m/s
Answer:
0.3 hours sooner than the normal time of arrival
Explanation:
Finding the difference in time of arrival of both speed will help know how much sooner.
Given:
Distance = 119 km
Speed 1 = 70 km/h
Speed 2 = 85 km/h
Time = Distance / Speed
For the time taken at the first speed
Time = 119/70
= 1.7 hours
For the time taken at the second speed
Time = 119/85
= 1.4 hours
∴ 1.7 hours - 1.4 hours
= 0.3 hours sooner
<span>The correct option is B): meters A and C. In fact, both A and C are ammeters. An ammeter is a device used to measure the current in a branch of a circuit. In order to work properly, an ammeter should be connected in series to a resistor, in order to have the same amount of current that passes through the resistor. In this circuit, we see that devices A and C are both connected in series to a resistor, so they are ammeters. Instead, devices B and D are connected in parallel, so they do not measure the current but the voltage (in fact, they are called voltmeter).</span>
