Answer:
I believe that it will be 10kg of water
Explanation:
Because a measure of the amount of information on a storage medium (tape or disk). For magnetic tape it is the amount of information recorded per unit length of tape (bits per inch or millimeter); for a disk, a fixed number of bits per sector, sectors per track, and tracks per disk.
The density in both the case will be equal, just the difference will be in the volume they occupy.
What is density?In practice, density is the weight of a substance per unit volume. Water has a density of about 1 gram per milliliter, but this varies depending on temperature and whether or not substances are dissolved in it. Because ice is less dense than liquid water, it floats in your glass.
This allows many aquatic organisms to survive the winter. If ice were more dense than water, it would continue to freeze and sink until the entire lake was frozen.
Any amount of water has the same density. Whereas one gram of water has a volume of one milliliter, ten grams have a volume of ten milliliters.
Thus, the density will be same.

Explain why a charged body loses its charge if we touch it with our hand?
if u answer me I can give u brainliest ☺️
Answer:
Explanation: A charged body loses its charge when we touch it with our hand because some of the charge flows through our body to the ground earthing. As a result the charge on the body decreases every time we touch it. This is because of earthing.
Explanation:

Explanation:
When we touch a charged body, it loses its charge, due to the process of earthing. Our body is a good conductor of electricity. It transfers the charges to the earth
What type of force causes the motion of an object to change
Answer:
Ok, so...... Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces. In the example below, the net force would be 900 Newtons (450 + 450 = 900), and the object would move to the right.
Explanation:
Answer:
Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces.

Answer:
Step-by-step Explanation:
Calculating net force
Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0

Which is heavier , a kilogram of lead or a kilogram of a polystyrene beads ?
Answer:
They weight the same, they're both 1 kilogram
The weight of the given objects is the same since they have equal mass.
Weight of object
The weight of an object is the gravitational pull of earth on the object. Weight is vector quantity because it varies from place to place due to difference in acceleration due to gravity.
The weight of 1 kg leadW = mg
W = 1 x 9.8
W = 9.8 N
The weight of 1 kg polystyreneW = mg
W = 1 x 9.8
W = 9.8 N
Thus, the weight of the given objects is the same since they have equal mass.

Answer:
I started answering this before everything was erases, but briefly
W = 1/2 K x^2 so K = 2 W / x^2 = 6 * 25 = 150
Also F = - K X = 150 * 1/5 = 30 N at max extension
m = F / a = 30 /15 = 2 kg
Since max extension occurs at t = 0 you can write
x = A sin ω t
v = ω A cos ω t
a = -ω^2 A sin ω t note that there is no phase angle here
Also at .1 compression
.1 = .2 sin ω t and sin ω t = 1/2 and ω t = 30 deg = pi / 6
Substiture these values above to get velocity and acceleration when
ω t = 30 deg
The kinetic energy of a body moving at a speed of 10 m / s is equal to 1000 J. What is the body mass
Answer:
m = 20 kg
Explanation:
Given that,
The speed of a body, v = 10 m/s
Kinetic energy of the body, K = 1000 J
We need to find the mass of the body. The formula for the kinetic energy of a body is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 1000}{(10)^2}\\\\m=20\ kg[/tex]

14. Saeed is pulling a 6 kg heavy rock with an upward force of 40 N but does not succeed to lift it up. What is the magnitude of the normal force on the rock?
Answer:
58.8 N
Explanation:
The normal force is calculated as equal to the perpendicular component of the gravitational force.
Thus; N = mg
We are given m = 6 kg
Thus;
N = 6 × 9.8
N = 58.8 N
Thus, magnitude of normal force on the rock = 58.8 N

A 96 kg man is standing in an elevator. The man experiences a net force when the elevator moves at an acceleration of 4.0 m/s2 upward and downward. Find both net forces
Answer:
The net upward force the man experiences is approximately 1,324.8 N
The net downward force the man experienced is approximately 556.8 N
Explanation:
The given mass of the man, m = 96 kg
The acceleration of the elevator, a = 4.0 m/s²
According to Newton's third law of motion which states that action ad reaction are equal and opposite, when the elevator moves upwards, we have;
The net force the man experiences, F = Gravitational force, m·g + The force of the elevator pushing upwards, m·a
∴ ↑F = m·g + m·a
Where;
F = The net force the man experiences
m = The mass of the man = 96 kg
g = The acceleration due to gravity ≈ 9.8 m/s²
a = The acceleration of the elevator = 4 m/s²
∴ ↑F = 96 kg × 9.8 m/s² + 96 kg × 4 m/s² ≈ 1,324.8 N
The net upward force the man experiences ≈ 1,324.8 N
When the elevator moves downwards, we have;
The net force the man experiences, F = Gravitational force, m·g + The loss of the gravitational force as the floor moves further downwards, -(m·a)
∴ F = m·g + -(m·a) = m·g - m·a
F = m·g - m·a
∴ ↓F = 96 kg × 9.8 m/s² - 96 k × 4 m/s² ≈ 556.8 N
The net downward force the man experienced ≈ 556.8 N
