So you would use the equation Q=cmΔT, where c is the specific heat, m is the mass, and ΔT is change in temperature. Q, or heat added, would equal (0.187)(2.5)(350-45), which simplifies to 142.5875 btu.
Answer:
friction force
Explanation:
force of friction is opposite to the force applied it resist the motion
Answer:
V = 48 Volts
Explanation:
Since we know that electric potential is a scalar quantity
So here total potential of a point is sum of potential due to each charge
It is given as

here we have potential due to 50 nC placed at y = 6 m



Now potential due to -80 nC charge placed at x = -4



Now potential due to 70 nC placed at y = -6 m



Now total potential at this point is given as

Answer:
Im pretty sure its 11 m/s east because it is 22 m/s hitting 11 m/s and the force is harder hitting
Explanation:
im not 100% sure becasue i did this stuff a while ago
