You're 6.0 m from one wall of a house. You want to toss a ball to your friend who is 6.0 m from the opposite wall.
The throw and catch each occur 1.0 m above the ground.
(Figure 1) Assume the overhang of the roof is negligible,
so that you may assume the edge of the roof is 6.0 m
from you and 6.0 m from your friend.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

An electric current is flowing through the cord below.what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

Could someone . i have tried to solve myself but my calculation is off
