106.5N
Explanation:
Given parameters:
Mass of cart = 75kg
Velocity = 4.4m/s
time taken = 3.1s
Unknown:
Force = ?
Solution:
To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".
F = m x a
F = force on body
m = mass of body
a = acceleration of the body
But we know that acceleration is the change in velocity with time of a body;
a = 
F = m x 
V is the velocity
t is the time taken
F = 
= 106.5N

Respuesta:
La respuesta más simple posible sería decir que toda la red alimentaria colapsaría y todos los organismos de la red morirían de hambre. ... Eso es porque la vida vegetal suministra la energía inicial al sistema de la red alimentaria. Sin plantas, no hay alimento para los herbívoros.

Answer:
5] Neutron: Charge= 0 Atomic mass unit = 1
10] <u>Hydrogen:</u>
Number of protons = 1
Number of neutrons = 0
Number of electrons = 1
Atomic number = 1
<u>Helium:</u>
Number of protons = 2
Number of neutrons = 2
Number of electrons = 2
Atomic number = 2
<em>Note:</em>
<em>Atomic number = proton number</em>
<em>Neutron number = Mass number - atomic number</em>
<em>Number of electrons = number of protons</em>

Answer: Intertidal zones are regions which lie above the water level which receives low tides. Estuaries are the closed bodies of coastal waters which contain brackish water.
Explanation:
The ways through which the intertidal zones and estuaries can be protected are as follows:
1. The chemical discharge from factories and sewage discharge must be restricted or prohibited in these areas so that the water and air quality remains good necessary for the survival of living beings.
2. Prohibiting the waterways to prevent the discharge of oils which can contaminate water of estuaries and soil of intertidal zones.
3. The trash of polythene bags, plastic materials, vegetable matter discharged from the city must be cleaned up to retain the quality of soil and water.
