B. 2 Km North, displacement is basically how far form the original place
Does height or distance affect impact?
You can test that and do your project about that or you can grow algae
Answer:
F = 39.36 N
Explanation:
given,
initial speed, u = 38 m/s
final speed, v = 0 m/s
mass of ball = 0.145 Kg
time, t = 0.14 s
Force = ?
using impulse formula
J = change in momentum
J = F x t
m(v - u) = F x t
0.145 x (0 - (-38)) = F x 0.14
F x 0.14 = 5.51
F = 39.36 N
force exerted by the ball is equal to 39.36 N.
Answer:
temperature, agitation (like stirring), adding a catalyst, etc.
The relationship between mass m, volume V and density d is:
The silver has density
, and the mass of the piece of silver is
. Therefore we can calculate its volume using the previous formula:
