It uses microwaves as little heatwaves and uses them to heat the food
They are lowest during the summer because warmer air is less dence
Answer:
θ = 33°
Explanation:
Here, we can use the formula for the total time of flight of a projectile to calculate the launch angle of frog:
where,
θ = launch angle = ?
T = Total time of flight = 0.6 s
g = acceleration due to gravity = 9.81 m/s²
u = launch speed = 5.4 m/s
Therefore,
<u>θ = 33°</u>
Answer:
Explanation:
Given that,
An object starts from rest at the origin (x₀ = 0) and travels in a straight line with a constant acceleration (a = constant).
The relation between the position (x) and time (t) is given by :
Let v is the velocity of the object.
Let a is the acceleration of the object. It is given by :
So, the acceleration of the object is . Hence, this is the required solution.
