Explanation:
Answer:
a)T total = 2*Voy/(g*sin( α ))
b)α = 0º , T total≅∞ (the particle, goes away horizontally indefinitely)
α = 90º, T total=2*Voy/g
Explanation:
Voy=Vo*sinα
- Time to reach the maximal height :
Kinematics equation: Vfy=Voy-at
a=g*sinα ; g is gravity
if Vfy=0 ⇒ t=T ; time to reach the maximal height
so:
0=Voy-g*sin( α )*T
T=Voy/(g*sin( α ))
- Time required to return to the starting point:
After the object reaches its maximum height, the object descends to the starting point, the time it descends is the same as the time it rises.
So T total= 2T = 2*Voy/(g*sin( α ))
The particle goes totally horizontal, goes away indefinitely
T total= 2*Voy/(g*sin( α )) ≅∞
T total=2*Voy/g
<u>Answer</u>:-
The main product is glucose despite as the matter of fact it produces several products such as:
•Oxygen
&
•Water too.
Explanation:
The reaction of photosynthesis is given below:
6CO2 + 12H2O + (in the presence of sunlight) → C6H12O6 + 6O2 + 6H2O
Carbon dioxide + Water + Sunlight → Glucose + Oxygen + Water.
Answer:
F = 309.24 N
Explanation:
Given that,
Charge on a strom cloud, q₁ = 0.055 C
The charge gained by the top of a tree, q₂ = -0.006 C
The cloud moves to 98 meters above the tree.
We need to find the amount of force between the cloud and the tree. The electrical force between two charges is given by :
So, the force between the cloud and the tree is equal to 309.24 N.
Answer:
In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, a force can cause an object with mass to change its velocity, i.e., to accelerate, or a flexible object to deform, or both.
