Answer: True
The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health
According to the current, the charge is 818.18 coulombs.
We need to know about current to solve this problem. Current can be defined as the flow rate of charge through the medium. It can be determined as
I = Q / t
where I is current, Q is charge and t is time.
From the question above, we know that
P = 25 W
V = 110 V
h = 1 hour = 3600 second
Calculate the current
P = V . I
25 = 110 . I
I = 0.23 A
By substituting the given parameters, we can calculate the charge
I = Q / t
0.23 = Q / 3600
Q = 818.18 coulombs
Hence, the charge is 818.18 coulombs.

Answer:
distance between the objects
masses of the objects
Explanation:
Gravitational force is a force of attraction that pulls two objects with masses together.
To best understand the concept of gravitational force, newton's law of universal gravitation provides a good insight. The law states that "every object in the universe attracts each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".
From the law, we see that gravitational force is dependent on the masses of the object and their distances.
Answer:
-22.5 m/s
Explanation:
= Mass of squid = 1.5 kg
= Mass of water ejected = 0.14 kg
= Velocity of squid = 0.4 m/s
= Velocity of squid after ejection = 2.5 m/s
v = Velocity of water ejection
In this system the momentum is conserved

The velocity of the water ejection relative to the squid is
-20+(-2.5) = -22.5 m/s
The negative sign indicates the opposite direction to the direction of the squid.
