Thermal energy in the form of fire is generated by the combustion of fuel. Due to the tendency of hot air to rise upward, the heat generated rises to fill the space of the balloon. One this space is full of trapped hot air, the heat's tendency to rise causes the hot air balloon to be lifted into the air.
<span>A. The buoyant force only acts on objects in water. - The buoyant force can act in ANY liquid, not just water
B. The buoyant force is always stronger than the force of gravity. - This is false. The buoyant force is dependent on the size of the object and not gravity
C. The buoyant force causes objects to sink more quickly than 9.8 m/s2. - This is false, since the buoyant force ALWAYS acts opposite of gravity.
D. The buoyant force always pushes objects up towards the surface of the fluid.
- This is true</span>
A would be the best answer beacuse
Ovaries - small, oval-shaped glands that are located on either side of the uterus. The ovaries produce eggs (ova - an ovum is one egg, ova means multiple eggs.) The ovaries also produce the main female sex hormones which are released into the bloodstream.
What is the question that you need help with
Answer:
W = 32.03316 N
Explanation:
given,
Amplitude, A = 34.7998 cm = 0.347998 m
spring constant, k = 13.5666 N/m
maximum speed, v = 70.8966 cm/s = 0.708966 m/s
acceleration due to gravity, g = 9.8 m/s²
weight of the banana = ?
using maximum speed formula
squaring both side
m = 3.26868 Kg
weight
W = mg
W= 3.26868 x 9.8
W = 32.03316 N
hence, weight of Banana is equal to W = 32.03316 N
