Need help finding the average on the trails i had did on range and velocity of projectile at ramp distance Ramp Incline 67 degrees

First Trial
Ramp distance 1.02
Trial measured distance (m)
1 1.10m
2 1.13m
3 1.15m
4 1.12m

What will be the average?

Ramp Incline 67 degrees

Second Trial
Ramp distance .90
Trial measured distance (m)
1 1.01m
2 1.04m
3 1.03m
4 1.03m

What will be the average?

Ramp Incline 67 degrees

Third Trial
Ramp distance .85
Trial measured distance (m)
1 .90m
2 .92m
3 .90m
4 .89m

What will be the average?

Which describes an image that can be produced by a concave lens? the image is real and smaller than the object. the image is virtual and larger than the object. the image is virtual and smaller than the object. the image is real and larger than the object.

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?
