B. accelerates in the direction of the force. this is because the force is now unbalanced, causing the object to move in that direction. it's like pushing a pen off the table. you applied force in that direction and since the pen doesn't have enough inertia to withstand your unbalanced force, it rolls off the table.
For the answer to the question above, it is A. Sea Breeze or <span>on shore, </span>breeze<span> is a gentle wind blowing from the </span>sea<span> toward land, that develops over bodies of water near land due to differences in air pressure created by their different heat capacity. It is a common occurrence along coasts during the morning as solar radiation heats the land more quickly than the water.</span>
<h3>right --- 20 + 10 = 30 N</h3>
<h3>left --- 10 N</h3>
<h3>resultant force --- 30 - 10 = 20 N</h3>
<h2>B. 20 N to the left</h2>
Answer:
V = 381.70 m³
Explanation:
ρ air = 1.28 kg / m³
ρ helium = 0.18 kg / m³
R = 4.5 m
Vb = 0.068 m³
mb = 123 kg
To determine the volume of helium in the balloon when fully inflated
V = 4 / 3 π * R ³
V = 4 * π / 3 ( 4.5 m )³
V = 381.70 m³
To determine the mass total
m = ρ helium * V
m = 0.18 kg / m³ * 381.70 m³
m = 68.70 kg
mt = ( 68.70 + 123 )kg
mt = 191.70 kg
