Answer:
Explanation:
A Spring stretches / compresses when force is applied on them and they are governed by the Hookes Law which states that the force required to stretch or compress a spring is directly proportional to the distance it is stretched.
F is the force applied and x is the elongation of the spring
k is the spring constant.
negative sign indicates the change in direction from equilibrium position.
In the given question, we dont have force but we know that the pan is hanging. We also know from the Newton's second law of motion that
Inserting this into Hooke's Law
computing it for x,
This is the model which will tell the length of the spring against change in the mass located in the pan.
Answer:
The net force acting on the bobsled is 300 N.
Explanation:
Given:
Mass of the bobsled is, 
Displacement is, 
Initial speed is, 
m/s
Final speed is, 
m/s
Net acceleration acting on the bobsled can be determined using the following Newton's equation of motion:
Plug in all the given values and solve for acceleration, 
.
Now, as per Newton's second law, net force is the product of mass and acceleration. So,
Therefore, the net force acting on the bobsled is 300 N.
Answer:
The current would stop
Explanation:
Electric currents are interesting because they carry little to no momentum. As soon as you remove a power source, the whole current halts.
Answer:
108 extended days
Explanation:
Regular school hours a day = 6 hr
No. of school days to make up by extending the regular hours = 3 days
Amount of time added to the regular hours of school = 10 min
No. of extended school days to make up the 3 school days by following the above mentioned criteria be x.
Time of school hours in 3 days = 
are required to make up 3 days of school having 6 hours of regular timing with 10 minutes of add-on time each day.
