Answer:
Explanation:
Height of building
H = 6m
Horizontal speed of first balloon
U1x = 2m/s
Second ballot is thrown straight downward at a speed of
U2y = 2m/s
Time each gallon hits the ground
Balloon 1.
Using equation of free fall
H = Uoy•t + ½gt²
Uox = 0 since the body does not have vertical component of velocity
6 = ½ × 9.8t²
6 = 4.9t²
t² = 6 / 4.9
t² = 1.224
t = √1.224
t = 1.11 seconds
For second balloon
H = Uoy•t + ½gt²
6 = 2t + ½ × 9.8t²
6 = 2t + 4.9t²
4.9t² + 2t —6 = 0
Using formula method to solve the quadratic equation
Check attachment
From the solution we see that,
t = 0.9211 and t = -1.329
We will discard the negative value of time since time can't be negative here
So the second balloon get to the ground after t ≈ 0.92 seconds
Conclusion
The water ballon that was thrown straight down at 2.00 m/s hits the ground first by 1.11 s - 0.92s = 0.19 s.
The main causes of convection currents in the asthenosphere are density and temperature.
Convection currents are formed from gradients such as concentration and temperature gradients. Density is the one closely related to concentration gradient .
Answer: Heat
Explanation: The transfer of heat or thermal energy occurs when there is a difference in temperature in a object or both. Heat moves from objects with higher temperature to objects with lower temperature. If both objects reaches the same temperature then they are said to be in thermal equilibrium, which means that there will be no more heat transfer between the objects.
Answer:
0.34 m/s^2
Explanation:
force=mass × acceleration
400 =1200 × acceleration
acceleration=400/1200
=0.34 m/s^2
Support and protect the body is NOT a function of the digestive system
Your body's skeletal structure serves as a support system. It gives the body its structure, permits mobility, produces blood cells, offers organs protection, and stores minerals. A different name for the skeletal system is the musculoskeletal system.
<h3>What is digestive system ?</h3>
The digestive system consists of organs that are crucial for breaking down both food and water. These include the anus, pharynx (throat), stomach, small and large intestines, rectum, and oesophagus.
- The body needs nutrients for energy, growth, and cell repair, and nutrients are broken down into via the digestive process. Prior to the blood absorbing nutrients from food and drink and transporting them to body cells, those nutrients must be broken down into smaller molecules.
