as i slide a box at constant speed up a frictionless slope, pulling parallel to the slope, the tension in the rope will be:

Answers

Answer 1

The strain in the rope will be less than the weight of the box when I pull parallel to the hill while sliding a box up it at a consistent speed.

We can observe from the preceding figure that the sine component of weight balances the tension force. Additionally, because the box is travelling at a constant speed, the block experiences no acceleration, and as a result, there is no net force acting on the block. (The block is in static equilibrium, for example) The force balancing equation may be written as T - mgsin0 =0=T= mgsin0 (a) The amount of strain won't be more than it would be if the box were stationary because there isn't any friction present in this situation.

(b,c,d) We may assume that the tension T will be smaller than the weight of the box since sin theta is between -1 and 1. Thus, the appropriate choice is (d)

what will be the slope of vs m graph when using the equation? where; t- period of one oscillation of the spring k- spring constant m- load hanging from the spring.

Answers

The slope of the plot of T vs. m is, m = (k/4π²).

The period of one oscillation of a spring-mass system is denoted by the letter T, and it is the time required for one complete cycle of motion, starting at any point in the cycle and returning to that same point.

The equation for the period T of a spring-mass system is, T = 2π √(m/k),

where k is spring constant and m is the mass of load hanging from the spring.

To find the slope of the plot of T vs. m, we can rewrite this equation in the form, T² = (4π²/k) m.

This is the equation of a straight line with slope, T = (k/4π²).

Therefore, the slope of the plot of T vs. m is, m = (k/4π²).

a student pushes against a wall until they are exhausted!!! (and obviously the wall doesn't move) has the student done any work on the wall?

Answers

No, the student has not done any work on the wall. Work is defined by physics as the transfer of energy from one object to another.

In this case, the student is exerting a force on the wall, but since the wall is not moving, no energy is being transferred and thus no work has been done.

Work is a fundamental concept in physics, and it can help us better understand how objects interact with each other and the environment around them. In a general sense, work is defined as the transfer of energy from one object to another, usually through the application of a force. This means that when a force is applied to an object, work is done on it and the object moves in the direction of the applied force.

julio intends to drive his motorcycle to a friends house 200 km away, if he increases his planned rate of speed by 10 km/h he can decrease his travel time by 40 min. what is his planned rate of speed

Answers

Julio's planned rate of speed would be 90 km/h (kilometers per hour).

This is calculated by taking the total distance (200 km) divided by the total time (2 hours minus 40 minutes, or 1 hour and 20 minutes). So, 200 km divided by 1.33 hours (1 hour and 20 minutes) is equal to 90 km/h.

Speed is a scalar quantity that measures how quickly an object is moving in a given direction. It is usually measured in units of distance per unit of time, such as miles per hour or meters per second. Speed is calculated by dividing the distance an object travels by the time it takes to travel that distance.

why is the current across a drain resistor the same as the current across drain to source in a mosfet

Answers

The current across a drain resistor is the same as the current across the drain to source in a MOSFET because the MOSFET behaves as a voltage-controlled resistor.

What is resistor ?

A resistor is an electrical component that is used to reduce the flow of current in an electrical circuit. It works by creating electrical resistance, which is measured in ohms. This resistance opposes the flow of current, allowing engineers to control the voltage and current levels in a circuit. Resistors are used in many different types of applications, from controlling the speed of motors to regulating the flow of current in digital circuits.

The resistance of the MOSFET channel is controlled by the voltage applied to the gate. If the gate voltage is increased, the resistance of the channel decreases, allowing more current to flow from the drain to the source. Since the drain resistor is in series with the MOSFET channel, the same current must also flow through the resistor.

what was the most important difference in development between isaac newton's theory of planetary motion and that of johannes kepler?

Answers

The most important difference in development between Isaac Newton's theory of planetary motion and that of Johannes Kepler was the explanation of why planets move in the way that they do.

Kepler's laws of planetary motion were based on extensive observations of the positions of the planets in the sky, and he discovered that planets move in elliptical orbits around the sun, with the sun located at one of the foci of the ellipse.

Isaac Newton, on the other hand, was able to provide a physical explanation for why planets move in elliptical orbits around the sun. Newton's law of universal gravitation stated that all objects in the universe are attracted to each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Using this law, Newton was able to demonstrate that the gravitational attraction between a planet and the sun causes the planet to move in an elliptical orbit.

If the angle is less than 90 degrees, the speed multiplier will be greater than 1, making the object move faster downhill. If the angle is greater than 90 degrees, the speed multiplier will be less than 1, making the object move slower uphill.

a 10,000 gallon water tank atop a building delivers fresh drinking water for its occupants. the top floor resident and the bottom floor resident are filling their bathtubs. assuming frictionless pipes and isothermal flow, which one will fill faster?

Answers

The bathtub on the bottom floor will fill faster assuming frictionless pipes and isothermal flow.

In an isothermal flow, the temperature remains constant and the pressure decreases as the height increases. This means that the pressure at the bottom floor is higher than the pressure at the top floor. As a result, the water will flow more quickly through the pipes to the bottom floor, filling the bathtub there faster.

This can be understood by considering the relationship between pressure and flow rate in a pipe: flow rate is proportional to the pressure difference. In this case, the pressure difference between the top and bottom floors is driving the flow of water, so the bathtub on the bottom floor will fill faster.
