What you know:
Vi=0m/s
Vf=143.8m/s
A=-9.8m/s
d=???
Use the equation Vf^2=Vi^2+2A(d)
Rearrange to isolate d: d=Vf^2/2A
d=(143.8)^2/2(-9.8)
d=20678.4/-19.6
d=-1055m
The tank was released from a height of 1055m
Answer:
A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption.
Explanation:
A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption.
To solve this problem we will apply the concepts related to the conservation of momentum. That is, the final momentum must be the same final momentum. And in each state, the momentum will be the sum of the product between the mass and the velocity of each object, then
Here,
= Mass of each object
= Initial velocity of each object
= Final velocity of each object
When they position the final velocities of the bodies it is the same and the car is stationary then,
Rearranging to find the final velocity
The expression for the impulse received by the first car is
Replacing,
The negative sign show the opposite direction.
ThermalThermal relief valve installed in a Hydraulic system will have the highest pressure setting.
<h3>What is the hydraulic system? What are the types of hydraulic systems ? </h3>
Hydraulic system function and perform tasks through using a fluid that is pressurized . There are two types of hydraulic systems open loop hydraulic systems and closed loop hydraulic system . In open loop ,when the actuating mechanism is idle ,there will be fluid flow but no pressure.
Closed loop system use an additional pump called charge pump or feed pump.
Thermal relief valve is Designed to protect the pump and operators in circumstances when the pump is running and the discharge outlets have been closed .
