The energy needs of a cell is very important because they need energy to breakdown,synthesis, and transport nutrients and molecules so an living organism can survive just like how the city needs energy to power its cities so it’s people can do what they need to do to survive. HOPE IT HELPS
Answer:
1244 students
Explanation:
That would be y = 82*3 + 998
= 1244.
Options :
The upward force is greater than the downward force.
The downward force is greater than the upward force.
The rightward force is greater than the leftward force.
The leftward force is greater than the rightward force.
Answer:
The downward force is greater than the upward force.
Explanation:
When the player jumps to dunk a basket ball, it requires an upward force exerted on the person due to the push by the person to jump, after dunking the basket ball, the player attains maximum height, where his final velocity becomes zero and his direction changes (from upward to downward), at this point his velocity increases due to the additional force exerted on the player due to the Earth's Gravitational pull - which is a downward force which acts on an object).
Hence, it could be concluded that the increase in speed of the basketball player as she returns to the ground means that the downward force is greater than the upward force acting on the player.
Answer:
Mass = 135.66 ×10⁻²¹ g
Explanation:
Given data:
Number of molecules of CuSO₄= 5.119×10²
Mass of CuSO₄= ?
Solution:
The given problem will solve by using Avogadro number.
1 mole contain 6.022×10²³ molecules
5.119×10² molecules ×1 mol / 6.022×10²³ molecules
0.85×10⁻²¹ mol
Mass in grams:
Mass = number of moles × molar mass
Mass = 0.85×10⁻²¹ mol × 159.6 g/mol
Mass = 135.66 ×10⁻²¹ g
