Hunter wants to measure the weight of a dumbbell. He should use a scale and record the weight in N.
Answer: Option D
<u>Explanation:</u>
The weight of an object refers the gravity force it affects, and this can be indicated as the mass multiplied by the acceleration due to gravity force, w = mg. Because weight is the force and so the unit is Newton. When you are not on weight, the net force on the scale and on the ground is zero, and the scale value (and normal strength) corresponds to the weight of the system. When you stand on the scale and raise or lower the bar, the center of gravity of the system rises and falls much more than the weight compresses or expands.
Therefore, the scale power (power) must be increased or decreased (the ground is solid) so that the center of gravity can move, raise and lower. When the center of gravity begins to move at a constant speed, the scale force decreases, matching the weight of the system. If you start to slow down and stop the dumbbell movement, the balance will change the weight again until you stop it. Hence, option D would be the right choice.
Answer:
Tides- the rise and fall of the oceans. Tides are caused by the gravitational pull of the moon on the water. Deconstructive waves- waves with a larger undertow than the actual waves coming in, taking sediment and other materials into the ocean.

Diagram 1 exhibits the nature of the particles within the state that forms after a solid melts. Solids melt into liquids and the particles within a liquid have a greater spacing than the particles in a solid. Moreover, these particles are free to slip over one another, which means that liquids do not have a definite shape; however, the particles are still confined in by intermolecular forces, which means that the volume of a liquid is definite.

a sulfur-32 atom contains 16 protons, 16 neutrons, and 16 electrons.
what is the mass (in grams) of a sulfur-32 atom?
The mass in grams of a sulfur-32 atom is 32.
That is how the isotopes are identified, showing the mass number of the isotope, which is the sum of protons and neutrons: 16 protons + 16 neutrons = 32 mass number = mass in grams of the isotope.
2. the mass of a
neutron is 1.67 x 10-24 g. approximately what number of neutrons would
equal a mass of one gram?
divide 1 gram by the number of neutrons per gram:
number of neutrons = 1 g / 1.67 * 10 ^ - 24 g / neutrons = 0.5998 * 10 ^ 24 neutrons = 5.998 * 10 ^23 neutrons.

Answer:
25
Explanation:
Step 1: Given data
Circumference of the running track (c): 400 m
Total distance completed during the race (d): 10 km
Step 2: Convert "d" to meters
We will use the conversion factor 1 km = 10³ m.
10 km × (10³ m/1 km) = 10⁴ m
Step 3: Calculate the number of laps to be completed (n)
We will use the following expression.
n = d/c
n = 10⁴ m/400 m
n = 25
