Answer:
increased greenhouse gases
Explanation:
I think this is the right answer...
Answer:
Explanation:
Let the initial speed be u . final speed = 0
v² = u² - 2gh
v is final speed , u is initial speed , h is height .
0 = u² - 2g x 134
u² = 2 x 9.8 x 134
u = 51.25 m /s .
From 1st EQ. of uniform motion
1)20.9-3.44/6=t=2.91 sec
2)28= 0+4.22a
a=6.66m/sec^2
3) Instantaneous acceleration
Answer:
The net force is 26.52 N
Explanation:
Given that,
Volume of balloon = 2.1 L
Density of air = 1.29 kg/m³
Mass = 1.3 g
Density of helium 
(a). We need to calculate the buoyant force on the balloon
Using formula of buoyant force

Put the value into the formula


(b). We need to calculate the net force
Using formula of net force



Hence, The net force is 26.52 N.
Can be made out of ; sand, rocks or soil if the current is not expected to be rough.
