Answer:
Option A
Lowering the amount of reactants
Explanation:
To reduce the rate of chemical reaction, one can reduce temperature or surface area. The addition of catalysts increases rate of reaction but decreasing the amount of reactants decreases rate of reaction. Therefore, from the choices provided, choice A is correct.
I would assume that the magnesium would have to come into contact with an ion in order to become a magnesium ion.
Answer:
it is 2.2 m
Explanation:
because he goes back 2.2 m so 4.4 minus 2.2 equals 2.2
Answer:
A. Their shape
Explanation:
The name clearly shows that the shape of these canals are semi-circular. The semi-circular canals consist of three tubes filled with fluid and located in the inner ear. They help to maintain balance and transmit impulses through the movement of the fluids. The impulses sent through these fluids are sent to the brain for interpretation.
The function of the canals are not indicated by the name, rather the shape is hinted through the name.
Answer:
The magnitude of the electric field strength = 7.2 x 10⁸ N/C
Explanation:
The linear density:
Point r = 3 cm = 3/100 m
r = 0.03 m
The electric field strength is calculated below
The magnitude of the electric field strength = 7.2 x 10⁸ N/C
