Answer choice c is the correct choice
Answer:
Weight = normal force = 24.5 N
Explanation:
Given that,
Mass of a dog, m = 2.5 kg
We need to find its weight and the normal force that it feels.
The weight of an object is given by :
W = mg
Where g is the acceleration due to gravity
The normal force is balanced by the weight of an object. So,
Weight = normal force = 24.5 N
Answer:
Explanation:
1) emf stands for elactro-motive force and represents the ability to move electrical charge carriers. Commonly referred to as Volts.
2) P = VI = 1.5(0.31) = 0.465 ≈ <u>0.47 W</u>
3) P = 0.465 - I²R = 0.465 - 0.31²(0.65) = 0.402535 W = J/s ≈ <u>0.40 J</u>
4) 14000 J / 0.40 J/s = <u>35 000 s </u> or about 9.75 hrs
<u>Answer:</u>
<h2>
Cold, Salty water.</h2>
<u>Explanation:</u>
The cold, salty ocean water is denser than the warmer water. Because of higher density, cold water sinks into the bottom of the ocean while warm water remains at the surface.
The sinking of the cold water at depth moving away from the surface generates deepwater currents by a process called upwelling. These deepwater currents bring the nutrient-rich water at the surface providing food and nutrients to marine life.
Answer:
the answer is well known as gravity
