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.
π(3.3)²×9.9 = 107.811π or approximately 338.7 cm³

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. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)Learn more:

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
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
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

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]

Answer:
15000kgm/s
Explanation:
Given parameters:
Speed of the car = 12m/s
Mass of car and passengers = 1250Kg
Unknown:
Momentum of the car = ?
Solution:
Momentum is the quantity of motion a body posses;
Momentum = mass x velocity
Now insert the given parameters and solve;
Momentum = 12 x 1250 = 15000kgm/s
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
What is the acceleration of a 7 kg mass pushed by a 3.5 N force?
Answer:
According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known
Explanation:
Which equation can be used to solve for acceleration?
t=v/a
vf=at-vi
a=d/t
v=a/t
Answer:
t=v/a
Explanation:
Acceleration is defined as the rate of change of velocity with time. It is mathematically expressed as;
Acceleration = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
The change in velocity per unit of time is the acceleration
From this equation;
time = [tex]\frac{change in velocity }{acceleration}[/tex]
This expression is analogous to the expression chosen.
which has an effect on acceleration (speeding up, slowing down, or changing direction)?
Explanation:
If acceleration points in the same direction as the velocity, the object will be speeding up. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.
