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
Carlo and Sara push on a desk in the same direction. Carlo
pushes with a force of 50 N, and Sara pushes with a force of
40 N. What is the total resultant force acting on the desk?
Whats the answer to this question?
Answer:
90N
Explanation:
The total resultant force acting on the desk being pushed by Sara and Carlo is 90N
A resultant force is a singular force that will act the same effect as the forces acting on a body.
When two or more forces acts on a body in the same direction, their resultant is the sum of the individual forces. If it is in the opposite direction, the differences is the resultant force. The body will move in the direction of the applied force with a higher magnitudeSo;
Resultant force = Force applied by Sara + Force applied by Carlo
Resultant force = 50N + 40N = 90N
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.
The one who waits for a shorter time wins. Neha leaves her pendulum from point L and Suhani leaves her pendulum from point P.Neha wins as her bob comes back faster. Therefore, option A is correct.
What is pendulum ?A weight suspended from a pivot such that it can freely swing is called a pendulum. Gravity's restoring force will cause a pendulum to accelerate back toward its equilibrium position if it is sideways moved from its resting, equilibrium position.
An object that is suspended from a fixed location by a string or rod and can move freely due to gravity and momentum. frequently used to control electronics like clocks. Simple pendulum: A back-and-forth swinging pendulum. A circularly swinging pendulum is referred to as a spherical pendulum.
The force of gravity acting on the swing causes it to move freely back and forth after being raised and released. The swing keeps returning.
Thus, option A is correct.

The tensile stress in a thick copper bar is 99.5 % of its elastic breaking point of 13.0× 10¹⁰ N/m² . If a 500-Hz sound wave is transmitted through the material, (c) What is the sound intensity in the bar?
Here the sound intensity in the bar is 4.73×10⁹ W/m².
What do you mean by sound intensity?The power carried by sound waves per unit area in a direction perpendicular to that region is known as sound intensity or acoustic intensity. The watt per square meter (W/m²) is the SI unit of intensity, which also covers sound intensity. One use for this technology is to measure the amount of sound energy present in the air near a listener.
According to the question:
The sound intensity in the bar, I = 1/2 ρω²s²v
I = 1/2 (8.92×10³)(2π×500)²(4.63×10⁻³)²(5010)
I = 4.73×10⁹ W/m².

Answer:
Newton's law of gravitation states that every object in this universe attracts every other object with a force called gravity,
when the distance between the two object is increased the gravitational force decreases by its square,
and when the mass an object increases the gravitational force also increases,
therefore, gravitational force is directly proportional to the mass of the two objects and is square inversely proportional to distance between them.

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.

How much force is required to accelerate an 8kg mass at 5m/s^2 if there is 14N of friction
Answer:
Explanation:
How much force is required to accelerate an 8kg mass at 5m/s^2 if there is 14N of friction.
Answer:
54 N
Explanation:
By Newton's second law the force acting on an object is related to its mass and acceleration
F = m x a where
where m = mass of the object and a is the acceleration
Here m = 8 kg and a = 5m/s² so
F = 8 x 5 =40 Newtons (measure of force)
But there is an opposite force due to friction of 14 Newtons
So net force required to overcome this friction and accelerate the object of mass 8kg to 5m/s² = 40 + 14 = 54 Newtons
