Answer:
V = (Vx^2 + Vy^2)^1/2 = (40^2 + 62^2)^1/2
V = 73.8 m/s
tan theta = Vy / Vx = 62/40 = 1.55
theta = 57.2 deg
Answer:
If you increase either mass or velocity, the momentum of the object increases proportionally.
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 .

Answer:
I have made a mistake in my answer
Answer:
Explanation:
Potential energy of a pair of charges
= k q₁q₂ /r₁₂
At r₁₂ = .125 m
= - 9 x 10⁹ x 2.4 x 4.3 x 10⁻¹² / .125
= - 743 x 10⁻³J
At r₁₂ = √2 x .275 m
- 9 x 10⁹ x 2.4 x 4.3 x 10⁻¹² / √2 x .275
= - 238.85 x 10⁻³J
= 239 x 10⁻³ J
Change = - 238.85 x 10⁻³ +743 x 10⁻³
= 504.15 x 10⁻³ J
B )
Work done by electric force will be same but in negative sign
= - 504.15 x 10⁻³ J
= - 504 x 10⁻³ J
