Response:
210.3 degrees
Justification:
The total force acting on charge A is 59.5 N
Apply the x and y components of the net force to determine the direction
atan (y/x)
<span>an atom is described as having a negatively charged electron cloud surrounding a positively charged nucleus, which is the correct choice.</span><span>
The nucleus contains electrically neutral neutrons and positively charged protons, establishing its positive charge. In contrast, electrons carry a negative charge. The electromagnetic force keeps the atoms bound to the nucleus.

The electric force between two objects is expressed as being proportional to the product of their charges and inversely proportional to the square of the distance separating them. In this instance, the distance between the first two charges is 19 cm. We formulate the equation k q1 q3/ (x)^2 = k q2 q3/ (19-x)^2, where x denotes the separation between q1 and q3. The charge q3 cancels out, and q2 is used in absolute terms. The resulting value of x is 5.79 cm.
the radiotracer transforms radioactive emissions into light for detection. the response is D.
Answer:
The surface area of the dog changes from A to 3A
Explanation:
It is stated that the dog's surface area has increased by a factor of 3 over four years.
We need to calculate the change in the relative surface area of the dog over this timeframe.
Let’s assume the initial surface area is A.
Since the surface area has been multiplied by 3,
it follows that the surface area after four years is equal to 3×A = 3A.
Thus, the dog's surface area transitions from A to 3A.
