Answer:
Exposing it to a very strong magnetic field
Explanation:
Aluminium is a non magnetic metal thus it is not magnetic under normal conditions. This is because it interacts with other magnets. The only condition that magnetism can be induced in aluminium is exposing it to a very strong magnetic field.

A cannonball with a perfect horizontal velocity of 80.0 m/s flies 320 m before hitting the ground. How much time was the cannonball in the air?
Time taken to reach height is 4 seconds.
Given that;
Velocity of cannon ball = 80 m/s
Height taken = 320 meter
Find:
Time taken to reach height
Computation:
S = ut + (1/2)gt²
320 = (80)(t) + (1/2)(10)(t²)
320 = 80t + 5t²
t² + 16t + 64
So,
t = 4
Time taken = 4 seconds

if the pumpkin is thrown from a height of 14 meters above the ground. the velocity of the pumpkin when it is thrown is 23 m/s at 40 degrees above the horizontal. what is the value of the horizontal velocity when the pumpkin is thrown
Answer:
The value of the horizontal velocity when the pumpkin is thrown is approximately 17.619 m/s
Explanation:
The height from which the pumpkin is thrown = 14 meters
The velocity with which the pumpkin is thrown = 23 m/s
The direction in which the pumpkin is thrown = 40° above the horizontal
The horizontal component of the velocity = 23 × cos(40) ≈ 17.619
Therefore, the value of the horizontal velocity when the pumpkin is thrown ≈ 17.619 m/s

Neon gas
Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement
A)
wood, water, neon gas
B)
wood, neon gas, water
water, wood, neon gas
D
water, neon gas, wood
Answer:
I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.
Answer:
A) wood, water, neon gas
Explanation:
wood, water, neon gas.
The particles of solids have an arrangement that is highly ordered and regular. Liquids have an arrangement that is less ordered, and the particle arrangement in gases is the least ordered and regular of the three states of matter.

Which best compares concave and plane mirrors?
Plane mirrors produce only virtual images, and concave mirr
Plane mirrors produce only real images, and concave mirror
Concave mirrors produce only real images, and convex mirro
Answer:
Explanation:
Hi! It would be A. Plane mirrors produce only virtual images,and concave mirrors produce real and virtual images.
Plane mirrors construct only virtual images, and concave mirrors make real and virtual images. Thus, this statement best corresponds concave and plane mirrors.
What are virtual images?A virtual image exists represented as the opposite of a real image, thus an image that cannot be obtained on a screen stands produced as a virtual image. The motivation for this exists in the fact that the beams of light that form a virtual image never connect therefore a virtual picture can never be projected onto a screen. Examples: Image formed in a plane mirror, an image constructed on the front and back surfaces of a spoon, etc.
Therefore, the (A) option exists as the accurate answer.

A can of corn heas a diameter of 6.6 centimeters and a height of 9.9 centimeters. How much corn can tue can hold?
Answer:
338.7cm
Explanation:
The can of corn would be in the shape of a cylinder. Since we are looking at capacity, we will want to find the volume.
V=abase×h
V=πr2×h
V=π(d2)2×h
V=π(6.62)2×9.9
V=338.7cm3
Hopefully this helps!
Answer:
338.7 cm³
Explanation:
For this question you use the volume formula of a cylinder πr²h.
Radius is 1/2 the diameter.
Simply input the variables into the formula.

Conduction
Convection
Radiation
None of these
Answer:
Radiation
Explanation:
The form of heat that does not require matter or particles to happen is known as radiation.
Radiation is a form of heat that is carried by electromagnetic spectrum. It does not depend on particles of the medium. Convection and conduction depends on the particles in the medium for heat transfer. Conduction and convection cannot occur in a vacuum. Radiation can transfer heat in a vacuum.An astronaut weighs 160 Newtons on the surface of of the moon where the acceleration due to gravity is 1.6 m/s/s. What is his weight on EARTH, where the acceleration due to gravity is 10 m/s/s? Include units in your answer. *
Answer:
The weight of an object with mass M, in a place with gravitational acceleration G, is:
W = M*G
We know that in the moon, with G = 1.6 m/s^2, the weight is 160N
Then we have the equation:
160N = (1.6 m/s^2)*M
With this, we can find the mass of the astronaut.
(160N)/(1.6 m/s^2) = M = 100kg.
Then in the Earth, where the acceleration is G = 10 m/s^2, the weight will be:
W = (10m/s^2)*100kg = 1000 N

a running person has a what you need. Mass of 60kg and a speed of 3.16m/s what is her kinetic energy?
Answer:
[tex]\boxed {\boxed {\sf 299.568 \ Joules }}[/tex]
Explanation:
Kinetic energy can be found using the following formula:
[tex]E_k=\frac{1}{2}mv^2[/tex]
where m is the mass and v is the velocity.
The mass of the person is 60 kilograms and the velocity is 3.16 meters per second
[tex]m= 60 \ kg \\v= 3.16 \ m/s[/tex]
Substitute the values into the formula.
[tex]E_k=\frac{1}{2} (60 \ kg) *(3.16 \ m/s)^2[/tex]
First, evaluate the exponent.
(3.16 m/s)²= (3.16 m/s) * (3.16 m/s) = 9.9856 m²/s²[tex]E_k=\frac{1}{2}(60 \ kg ) (9.9856 \ m^2/s^2)[/tex]
Multiply 60 kg by 9.9856 m²/s²
[tex]E_k=\frac{1}{2} (599.136 \ kg*m^2/s^2)[/tex]
Multiply 599.136 kg*m²/s² by 1/2, or divide by 2.
[tex]E_k=299.568 \ kg*m^2/s^2[/tex]
1 kg*m²/s² is equal to 1 Joule Therefore, our answer of 299.568 kg*m²/s² is equal to 299.568 Joules.[tex]E_k= 299.568 \ J[/tex]
The running person has a kinetic energy of 299.568 Joules.
Solution:
We know that, Kinetic energy(kE)= 1/2×m×v^2
By applying formula,we get
Or,KE=1/2×60×3.16^2
Or,kE=299.57j
So,her kinetic energy is 2999.5j
What is the mass in grams of 3.1 mol of mercury, Hg Show Your work
Answer:
621.83grams
Explanation:
Using the formula;
Mole = mass ÷ molar mass
Where;
Mole = mol
Mass = grams
Molar mass = g/mol
According to the information given in this question, number of moles = 3.1mol, mass of Hg = ?, Molar mass (MM) of Hg = 200.59g/lol
Hence, using mole = mass/MM
3.1 = mass / 200.59
mass = 200.59 × 3.1
Mass = 621.829
Mass = 621.83grams

Answer:
0.6 seconds
Explanation:
The time to fall from height h is ...
t = √(2h/g)
t = √(2(1.86 m)/(9.8 m/s^2)) ≈ √0.3796 s ≈ 0.616 s
It would take about 0.6 seconds for the projectile to hit the ground.

24. A soccer ball is kicked straight up into the air with a velocity of 10 m/s. How much time does it take the ball to reach its maximum height? (g = 10 m/s^2)
A 2 sec
B 100 sec
C 1.4 sec
D 1 sec
Answer:
D. Time t = 1 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.
[tex]v_{f}=v_{o}-g*t[/tex]
where:
Vf = final velocity = 0 (when the ball reaches the maximum height its elevation won't be increased since the velocity is zero)
vi = initial velocity = 10 [m/s]
g = gravity acceleration = 10 [m/s²]
t = time [s]
Now replacing:
[tex]0 = 10-10*t\\10 = 10*t\\t = 1 [s][/tex]

Neha and Suhani are playing with two identical pendulums. They leave the bob from a certain position and wait for it to return to the same point. The one who waits for a shorter time wins. Neha leaves her pendulum from point L and Suhani leaves her pendulum from point P (see figure). What happens?
a. Neha wins as her bob comes back faster.
b. Suhani wins as her bob comes back faster.
c. No one wins as the bobs come back at the same time.
d. We cannot say any of the above for sure.
Answer:
The correct option is C
Explanation:
The pendulum bob would return at the same time because the initial angle a pendulum bob is dropped does not affect it's period (the time it takes for the pendulum to move back and forth), however the one with a larger angle move faster but would eventually arrive at the same "starting point" due to varying displacements made.
c. No one wins as the bobs come back at the same time.
The pendulum bob would return at the same time because the initial angle a pendulum bob is dropped does not affect it's period (the time it takes for the pendulum to move back and forth), however the one with a larger angle move faster but would eventually arrive at the same "starting point" due to varying displacements made.The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum.
