Answer: The Earth's layer, which has the covering and layer, is made of a progression of things, or structural plates, that creep after some time. Along these lines, at intersecting limits, mainland outside is made and maritime covering is devastated. 2 plates slippy past each other structures a redesign plate limit.
Choice A ... I = V/R ... is a correct form of Ohm's Law.
A :-) for this question , we should apply
F = GMm by d^2
( For making the calculation easy , first remove the decimals )
Given : G = 6.7 x 10^-11 Nm^2 / kg^2
= 67 x 10^-12 Nm^2 / Kg^2
M = 65 kg
m = 40 kg
d = 0.5 m
Solution -
F = GMm by d^2
F = 67 x 10^-12 x 65 x 40 by 0.5 x 0.5
F = 4355 x 40 x 10^-12 by 0.25
F = 174200 x 10^-12 by 0.25
F = 696800 x 10^-12
.:. The Gravitational force between mark and Katie is 696800 x 10^-12
Answer:
5 N
Explanation:
Archimedes' principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces.
In this case, The weight of an object in air is 20N and it weighs x N when fully immersed in water. So, the weight of the water displaced is given as;
20 − x = 5
Therefore, the weight of the body in water is 5 N.
Answer:
Total distance traveled= 75.36km (point at which she reaches her destination.)
Explanation:
With the speed and time data we can calculate the distance traveled on each path, but first we must transform the time units from minutes to hours:
First ride:
v=80km/h t=25min*1h/60min=0.42h
distancie= v*t = 80km/h * 0.42h =33.6km
Second ride:
v=65.0km/h t= 20min*1h/60min= 0.33h
distance= 65.0km/h*0.33h=21.67km
Stop: 60min= 1h distance=0km
third ride:
v= 40.0km/h t= 30.0min *1h/60min= 0.5h
distance= 40.0km/h*0.5h=20km
Total distance traveled= 33.6km +21.76km+20km
Total distance traveled= 75.36km
