Answer:
<h2>76°</h2>
Explanation:
In projectile,
Maximum height =
and range = 
u = velocity of the body
= angle of launch
g = acceleration due to gravity
If the range equals the maximum height in an ideal projectile launch on a horizontal plane, this means;

since 

The angle at which the range equals the maximum height in an ideal projectile launch on a horizontal plane is approximately 76°
The answers are 'muscle shrinkage' and 'decreased muscle cavity'. This is why unhealthy astronauts cannot go to space because it can be detrimental to their health.
Answer:
B. They are the electrons that interact with other atoms.
Explanation:
Valence electrons are the electrons in the outermost shell of an atom. These electrons are used by atoms to form bonds with other atoms during chemical bonding.
- So, the basis by which atoms interacts with one another is through the valence electrons.
- Without the valence electrons, atomic combination to form compounds would not be possible.
- Valence electrons are the most loosely held electrons and they have the lowest ionization energy.
If a point has 40 J of energy and the electric potential is 8 V, the charge must be: A. 5 C
<u>Given the following the details;</u>
- Electric potential = 8 Volts
To find the quantity of charge;
Mathematically, the quantity of charge with respect to electric potential is given by the formula;

Substituting the values into the formula, we have;

<em>Quantity of charge = 5 Coulombs</em>
Therefore, the quantity of charge must be <em>5 Coulombs.</em>
