The Correct answer to number 1 is A or D
The correct answer to number 2 is C because transmission meaning is to travel.
PS. I think number 1 is D
Answer:
7.06MN
Explanation:
length = 60m
Width = 10m
Height = 12 m
Let Fb = Force buoyant
Fb = pgV = mg
p(density) = rho
The density of water in this case = 1000
g = 9.8 m/s
Volume = lenght*width*height
= 60*10*12
= 7200m^3
So we have
(1000 * 9.8 * 7200) = mg
= 70560000
7.06 MN
F = G m1*m2 / r^2 => [G] = [F]*[r]^2 /([m1]*[m2]) = N * m^2 / kg^2
That is one answer.
Also, you can use the fact that N = kg*m/s^2
[G] = kg * m / s^2 * m^2 / kg^2 = m^3 /(s^2 * kg)
Answer:
2g
Explanation:
A half-life means after a certain amount of time, half of that substance will be gone/changed after that time.
So, we divide the 16g sample in half 3 times.
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
There will be 2g of the radioactive sample remaining after three half lives.
(hope this helps can i plz have brainlist :D hehe)
