Answer:
0.02 m
Explanation:
R₁ = initial distance jumped by jumper = 7.4 m
R₂ = final distance jumped by jumper = ?
θ₁ = initial angle of jump = 45°
θ₂ = final angle of jump = 42.9°
= speed at which jumper jumps at all time
initial distance jumped is given as
final distance jumped is given as
Dividing final distance by initial distance
distance lost is given as
d = 
d = 7.4 - 7.38
d = 0.02 m
The shape of which the pebble sized particles that makes up the rock is more of a rounded shape as they are bits and in circular formation, depicting it to be more rounder in which are particles that is made up in a rock. They can be in pebble sized or much more smaller than that when in bits.
Answer:
A. not excludable and not rival in consumption.
Explanation:
Answer: E = 39.54 N/C
Explanation: Electric field can be determined using surface charge density:
where:
σ is surface charge density
is permitivitty of free space (
)
Calculating resulting electric field:
![E = \frac{[0.3-(-0.4)].10^{-9}}{2.8.85.10^{-12}}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B%5B0.3-%28-0.4%29%5D.10%5E%7B-9%7D%7D%7B2.8.85.10%5E%7B-12%7D%7D)
E = 39.54
The resulting Electric Field at any point is 39.54N/C.
