Answer:
19. down
20. True
Explanation:
The examples I saw were projectiles launched at different angles and speeds. In each case, the only acceleration was ...
19: down
20: due to gravity (true)
Answer:
F₀= 12 mg θ = 85.2º
Explanation:
When the force is applied the pendulum moves laterally, and the tension in the rope has components that reached a point balances the horizontal force. Let's apply make sure Newton
X axis
F -Tx = 0
F = Tx
Axis y
Ty -W = 0
Ty = W
Let's look for the tension components
cos θ = Ty / T
sin θ =Tx/T
Ty = T cos θ
Tx = T sin θ
Let's replace and solve the system of equations
F = T sin θ
mg = T cos θ
F / mg = tan θ
tan θ = 12 mg / mg
θ = tan -1 12
θ = 85.2º

The correct answer is option 2. Systems, by
nature, tend to undergo changes toward higher entropy and lower energy since
this is the state where they are most stable. Entropy is the degree of
disorderliness of a substance. Systems tend to go to higher disorder since
systems always tend to change which can be linked to disorder and is
inevitable.
Answer:193.90 m/s
Explanation:
Given
launch angle
launch velocity
Horizontal velocity of the shell after
time of flight of Projectile
i.e. projectile is declining as
but horizontal component of velocity will remain same as there is no opposing force in horizontal direction
Horizontal component of velocity is
