Answer:
The sun looks bigger than other stars because it is closer to the Earth, distance makes it look larger
E = mass x gravity x height
Answer:
u = 10.63 m/s
h = 1.10 m
Explanation:
For Take-off speed ..
by using the standard range equation we have

R = 9.1 m
θ = 26º,
Initial velocity = u
solving for u



u = 10.63 m/s
for Max height
using the standard h(max) equation ..



h = 1.10 m
<em>number of waves that pass a given point in one second is called <u>frequency..</u></em>
