Answer:
(C) greater than zero but less than 45° above the horizontal
Explanation:
The range of a projectile is given by R = v²sin2θ/g.
For maximum range, sin2θ = 1 ⇒ 2θ = sin⁻¹(1) = 90°
2θ = 90°
θ = 90°/2 = 45°
So the maximum horizontal distance R is in the range 0 < θ < 45°, if θ is the angle above the horizontal.
A sound wave’s amplitude relates to changes in pressure. The sound is pecieved as louder if the amplitude increases, and softer if the amplitude decreases.
Answer:
...
Explanation:
sigh its not that hard
Any liquid takes form of the shape of the container it goes into.

Solids are already a shape so it cant take the shape of the container if it already has one. yk
Answer:
2 to 4 hours
Explanation:
Given that,
Microbial food infections
We know that,
Food infection :
When we eat old food, uncooked, fermented food, more junk food and contaminated food then 2 to 4 hours after eating we started vomiting, headache then we affected by food infections.
So, we can say that microbial food infections are usually not seen until 2 to 4 hours after eating contaminated food.
