how does the thickness of wood affect its stability
Answer:
Making the lumber thick will make it stiff, which seems good. On the other hand, with thicker lumber, differences in expansion on the two faces have more leverage to make the lumber move.
Newton's first law of motion: Objects in motion will stay in motion and objects at rest will stay at rest, unless acted on by
a. friction
b. acceleration
c. unbalanced force
d. contact force
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia
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.

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 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

Which forms of heat transfer do not require matter(particles) to happen? (Select all that apply)
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.Please help me on my test :) thank uu

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

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

Calculate the force between two objects that have masses of 70 kilograms and 2,000 Kilograms separated by a distance of 1m
Answer:
The gravitational force between two objects = F = 9.3 x 10⁻⁶ N
Explanation:
Given
m₁ = 70 kg
m₂ = 2000 kg
distance r = 1 m
Thus, the gravitational force between two objects = F = Gm₁m₂ / r²
as
Gravitation constant = G = 6.67430×10⁻¹¹ N⋅m²/kg²
Thus, putting the values
F = Gm₁m₂ / r²
= (6.67430×10⁻¹¹ × 70 × 2000) / 1²
= 9.3 x 10⁻⁶ N
Thus, the gravitational force between two objects = F = 9.3 x 10⁻⁶ N

Height of cannon 5 m, initial speed of projectile 15m/s, angle of launch 0 degrees. What is the range and time in the air? Please show work!
Answer:
The range is 15.15 m and the time in the air is 1.01 s
Explanation:
Horizontal Motion
When an object is thrown horizontally (with angle 0°) with a speed v from a height h, it follows a curved path ruled exclusively by gravity until it eventually hits the ground.
The range or maximum horizontal distance traveled by the object can be calculated as follows:
[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]
To calculate the time the object takes to hit the ground, we use the equation below:
[tex]\displaystyle t=\sqrt{\frac{2h}{g}}[/tex]
The cannon is shot from a height of h=5 m with an initial speed of v=15 m/s. The range is calculated below:
[tex]\displaystyle d=15\cdot\sqrt{\frac {2*5}{9.8}}=15*1.01[/tex]
d = 15.15 m
The time in the air is:
[tex]\displaystyle t=\sqrt{\frac{2*5}{9.8}}[/tex]
t = 1.01 s
The range is 15.15 m and the time in the air is 1.01 s
What are the two forces that act on the orbit of a planet?
A) Velocity of planet and gravity between sun and planet.
B) Gravity between the aphelion and perihelion.
C) Gravity between planet and sun and the velocity of the sun.
D) Orbits of other planets and gravity between sun and planet.
HELP PLEASE!
The two forces that act on the orbit of a planet are velocity of planet and gravity between sun and planet.
What is gravity?The force that pulls items toward the center of a planet or other entity is called gravity. All of the planets are kept in orbit around the sun by gravity. Gravity applies to everything that has mass. Gravity is stronger for objects with higher mass. Along with distance, gravity weakens as well. Therefore, the gravitational pull of two things becomes stronger the closer they are to one another.
The mass of the Earth is what creates gravity. The combined gravitational force of all of its mass acts on the mass in your body.
Velocity of the planet is also related to its gravity.
Forces that acts on the orbit of a planet is force due to velocity and gravity.
