If im not mistaken it is true
Answer:
4.17 m/s
Explanation:
To solve this problem, let's start by analyzing the vertical motion of the pea.
The initial vertical velocity of the pea is
Now we can solve the problem by applying the suvat equation:
where
is the vertical velocity when the pea hits the ceiling
is the acceleration of gravity
s = 1.90 is the distance from the ceiling
Solving for ,
Instead, the horizontal velocity remains constant during the whole motion, and it is given by
Therefore, the speed of the pea when it hits the ceiling is
Lighting gives a sense of scale (The sky)
Answer:
b 15
Explanation:
the atomic number is the number of the element
The best answer would be:
B. Epi pen
Here is more about it:
An epi pen injects epinephrine into the body to counteract the effects of an allergic reaction. Epinephrine helps narrow blood vessels and open up the airways. This can be used for food allergies, insect bites, and some other allergens. It is very effective and immediately works, but it is short-lived, so seeking medical attention after is still needed.
