Answer:
The correct option is d, bactericidal
Explanation:
Antimicrobial agent that kill bacteria are called bactericidal and hence, prevents the growth of bacteria.
Antimicrobial agent that slows the growth of the bacteria called bacteriostatic.
Bactericidal and bacteriostatic are types of antibiotics.
Bactericidal antibiotics act by inhibiting cell wall synthesis. Penicillin, cephalosporins, vanomycin, etc are some of bactericidal antibiotics.
Option 4 . Energy is transferred to the tree in this wave.
Explanation:
The figure shows that the rope is tied to tree at one end and at the other end a boy is holding it.
Here the boy swings the rope to give it a sudden movement and due to this movement the transverse waves of sinusoidal form are obtained and gets traveled till the tree.
Here the energy used by the boy to give a quick movement to the rope gets transferred till the other end of the rope that means the energy is getting transferred to the tree.
Along with the energy the particles of the way also gets transferred to the tree unless there is an obstacle.
Therefore in this wave energy is transferred to the tree.
Answer:
D.) 2.5 moles
Explanation:
To find the moles of H₂, you need to multiply the given value by the mole-to-mole ratio. This ratio consists of the coefficients in front of the relevant molecules. It is important to arrange the ratio in a way that allows for the cancellation of units.
1 Mg + 2 HCl -----> MgCl₂ + 1 H₂
^ ^
2.5 moles Mg 1 moles H₂
----------------------- x --------------------- = 2.5 moles H₂
1 mole Mg
(4) temperature is the correct answer.
Average kinetic energy is calculated by 3/2*R*T, in which R is a constant and is equal to 8.3145 J/ mol*K, and T is temperature measured in Kelvins.
Hope this helps~
