If you pull up on a bucket with a tension force of 15 N and the bucket has a weight of 15 N, what is the net force acting on the bucket?
15 Nup
15 N down
30 N up
O N
Answer:
F = 0 [N]
Explanation:
To solve this problem we must perform a summation of forces in the direction of the vertical axis. Where the positive force is that of the tension of the upward force, while the force exerted by the weight is directed downward with a negative sign.
ΣF = 0
15 - 15 + F = 0
F = 0 [N]
The focal length of a converging lens is the distance.
The distance from the lens to the focal point is called the focal length.
What is a converging lens?Converging lenses, commonly referred to as convex lenses, have thicker centers and narrower upper and lower margins. The edges are outwardly curled. This lens has the ability to concentrate a beam of parallel light rays coming from the outside onto a spot on the opposite side of the lens. Convex lenses come in three different varieties, each with a unique structure.Convex mirrors are used in a car's side wing mirrors and rearview mirrors. This is so that the driver can see a wider area than the average person because of the distorted image that is created. aids the driver in keeping a closer eye on the road and vehicles in the back.Due to the greater field of view, it provides than usual, it is also utilized in driving mirrors and store security mirrors. Using blind corner mirrors to see around blind corners on the road is advantageous. By being able to see the traffic around tight turns, it improves road safety.To learn more about converging lens, refer to

Answer:
A
Explanation:
According to Newton's second law, acceleration is directly proportional to the net force. As the acceleration increases (when mass is constant), the net force increases. This is represented in the following formula.

Explanation:
Two boxes of textbooks, of masses 10 kg and 15 kg, are connected by a lightweight string, and then pulled across a horizontal table by a horizontal applied force, as shown in the diagram above (attached to question).
The applied force has a magnitude of 50 N, and there is no friction between the boxes and table. What is the acceleration of the 10 kg 10 kg box?
A.) 3.3 m/s^2
B.) 2.0 m/s^2
C.) 5.0 m/s^2
D.) The box will not accelerate because the tension force acting on it to the left must also be 50 N 50 N.
Answer:
The correct option is;
B.) 2.0 m/s²
Explanation:
The given information are;
The masses of the boxes are; m₁ = 15 kg and m₂ = 10 kg
The force applied, F = 50 N
The friction force between the blocks and the table = N/A
The equation for the applied force, F = Mass, m × Acceleration, a
Therefore;
a = F/m
Given that the two boxes are attached to each other and to the force by a spring, they will experience the same motion, and therefore, the same acceleration
The total mass (the two blocks) pulled by the applied, 50 N force, [tex]m_T[/tex] = m₁ + m₂ = 10 kg + 15 kg = 25 kg
The acceleration given the blocks by the applied force, a = F/[tex]m_T[/tex] = 50 N/(25 kg) = 50 kg·m/s²/(25 kg) = 2 m/s²
The acceleration experienced by the 10 kg box = The acceleration experienced by the system of the two boxes = 2 m/s².

What are the similarities of gravity and air resistance?
Answer: Gravity or Air Resistance. As you saw and read on the previous screens, the force of gravity causes an object to accelerate toward the ground. However, the force of air resistance counteracts gravity and affects how fast an object falls. In this activity, you will compare the forces of gravity and air resistance.

An ultra-low friction pulley deal is as shown. The two weights experience an acceleration of 3.8m/s2. The first weight has 1.08kg. Find the mass of the second weight
Answer:
The mass of the second weight is approximately 0.477 kg
Explanation:
The given parameters are;
The acceleration experienced by the two weights = 3.8 m/s²
The mass of the first weight = 1.08 kg
The formula for the acceleration, a, of weights attached to a friction pulley, is given as follows;
[tex]a = \dfrac{g \cdot (M - m)}{M + m}[/tex]
Where;
a = The common acceleration of the two weights
g = The acceleration due to gravity = 9.81 m/s²
M = The mass of the first weight = 1.08 kg
m = The mass of the second weight
Therefore, we have;
[tex]m = \dfrac{M\cdot (g -a )}{g + a} = \dfrac{1.08\times (9.81 -3.8 )}{9.81 + 3.8} \approx 0.477[/tex]
The mass of the second weight = m ≈ 0.477 kg
The mass of the second weight ≈ 0.477 kg.

An engineer must design a runway to accommodate airplanes that must reach a ground speed velocity of 61 m/s before they can take off. These planes are capable of accelerating at a rate of 2.5 m/s2.
a.) How long will it take the planes to reach takeoff speed?
b.)What must be the minimum length of the runway?
a) It will take 24.4 second the planes to reach takeoff speed.
b) The minimum length of the runway must be 744.2 meter.
What is acceleration?Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.
Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.
Given parameters:
Acceleration of the plane: a = 2.5 m/s².
Final speed of the plane: v = 61 m/s.
Initial speed of the plane: u = 0 m/s.
Hence, it will take the planes to reach takeoff speed = final speed/acceleration
= 61 m/s / 2.5 m/s²
= 24.4 second.
The minimum length of the runway must be = (final speed)²/(2×acceleration)
= ( 61)²/(2×2.5) meters
= 744.2 meter.

What is a metal?????????
Answer:
A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride.
