At the top of the loop, the direction of the force exerted on a 55 kg rider by the roller-coaster seat is downward.

A roller coaster is a theme park ride where passengers travel in cars attached to a track, typically in the form of a roller coaster's archetypal loop-the-loop.The roller coaster is an example of a system that obeys the laws of physics. Inertia, gravity, and energy are the three key principles involved in roller coaster physics. Gravity is the most important force at work on a roller coaster.

At the top of the loop, the direction of the force exerted on a 55 kg rider by the roller-coaster seat is downward. This is due to the centripetal force that acts on the rider and causes them to travel in a circle. At the top of the loop, the force of gravity is pulling the rider downwards, while the centripetal force provided by the seat is pushing them upwards and inwards towards the center of the loop.

Answer: Force required to 25 joule work when the force causes a displacement of 0.5m is 50N

Explanation: To calculate the work done we use the formula

W=F.s                               (1)

W= work done

F=  force applied               s= displacement

Given, work done W= 25 joules= 25 J

displacement s= 0.5m

∴From equation (1) we get the force required when work is done and displacement is given, that is

F\(=\frac{W}{s}\)                                (2)

∴Force required \(F=\frac{W}{s}= \frac{25J}{0.5m}=50N\)            

(1 J is the work done by a force of 1 N acting over a displacement of 1 m and so 1 J= 1 Nm⇒ 1 N = 1 J/m)

ANS: Force required to do 25 J work when a force causes displacement of 0.5m = 50 N

Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.

Explanation:

Answer:

1. The speed of the wave is affected by wavelength frequency because waves travel through a medium and sound, ocean waves and seismic waves, etc. are the physical properties of the medium that determines the speed of the mechanical waves.

2. I think the frequency of the wave doesn't have any effect on the wave speed. Only the characteristics of the medium the wave is traveling through determines its speed.

3. As a wave moves from a medium of low density to a higher density the wave speed increases and when a wave moves from a higher density to a medium density the wave speed decreases because the wave length shortens causing the wave speed to lower.

4.If the instrument is initially flat they should tighten it because once it is tightened there is going to be force applied to the gears, and after you've reached the correct pitch the gears won't be able to move. So ultimately, you will be able to meet the intended pitch you were going for.

In geophysical surveys, to measure the Earth's magnetic field, to find different kinds of magnetic anomalies, and to calculate the dipole moment of magnetic materials, magnetometers are frequently used.

You can measure the magnetic field at a specific location in space using a magnetometer, also known as a gaussmeter. The direction of the magnetic field can also be measured by some devices. Midway through the 1800s, these devices were created, and they have since developed into precise, accurate measurement tools.

Every type of aircraft and spacecraft needs a magnetometer, also referred to as a magnetic sensor, to measure magnetic induction (magnetic field intensity).

Changes to temperature or pH can change enzyme activity due to the fact that enzymes are sensitive to their environment. As the temperature or pH of the environment is altered, the structure of the enzyme molecule can be affected, leading to changes in enzyme activity.

Changes to temperature or pH can affect enzyme activity because they can alter the structure of the enzyme. Enzymes are proteins, and their structure is crucial to their function. Changes to temperature can cause enzymes to denature, or lose their structure, which in turn affects their ability to catalyze reactions. Similarly, changes to pH can also affect the structure of the enzyme, as it can change the charges on the amino acids that make up the enzyme. This can also lead to a loss of function. Therefore, it is important for enzymes to be in an environment with the optimal temperature and pH for them to function properly.

According to Newton's second law, F = ma and F2 (= (60)(22500) (= 1350000 N. The total force needed to stop an unbuckled or air bag-using person is 135000 N.

They make it harder for cars to stop quickly after collisions (like an airbag). The passengers feel less force as a result. Because the car's distortion (crumpling) absorbs from the accident, less energy is transferred to the occupants.

What is the secret of using force, Newton's second laws of motion provides the definition of the force formula: An object's force is equal to its mass times its acceleration. F = m ⨉ a. To apply this formula, you must use SI units for force (newtons), mass (kilogrammes), and acceleration (metres per second squared).

Answer: 1

Explanation:

The x-component of the net force on q2 is -1.439 × 10^-10 N.

The given charges are Q1 = -4.60 * 10^-6 C, q2 = +3.75 * 10^-5 C, and q3 = -5.30 * 10^-6 C. We need to find the x-component of the net force on q2.

The formula for force is F = K(q1 * q2) / r^2, where K is Coulomb's constant = 8.99 × 10^9 Nm^2/C^2, q1 and q2 are the charges in Coulombs, and r is the separation distance in meters.

The force between q2 and Q1 on the x-axis can be calculated as:

F1 = K(Q1 * q2) / r^2 ... (i)

Here, K = 8.99 × 10^9 Nm^2/C^2, Q1 = -4.60 × 10^-6 C, q2 = 3.75 × 10^-5 C, and r = 0.05 m.

Calculating F1:

F1 = (8.99 × 10^9) * (-4.60 × 10^-6) * (3.75 × 10^-5) / (0.05)^2

F1 = -1.242 × 10^-10 N

Similarly, the force between q2 and q3 on the x-axis can be calculated as:

F2 = K(q2 * q3) / r^2 ... (ii)

Here, K = 8.99 × 10^9 Nm^2/C^2, q2 = 3.75 × 10^-5 C, q3 = -5.30 × 10^-6 C, and r = 0.06 m.

Calculating F2:

F2 = (8.99 × 10^9) * (3.75 × 10^-5) * (-5.30 × 10^-6) / (0.06)^2

F2 = -1.971 × 10^-11 N

The net force can be calculated by adding F1 and F2, considering their x-components:

Fnet = F1 + F2

Fnet = (-1.242 × 10^-10) + (-1.971 × 10^-11)

Fnet = -1.439 × 10^-10 N

As both forces act in opposite directions along the x-axis, the net force is in the negative x-direction.

To find the t-values for the given areas and degrees of freedom, we can use the t-distribution table or a statistical calculator. Here are the answers:

(a) Finding the t-value for an area of 0.10 in the right tail with 25 degrees of freedom:

Using symmetry, we know that the area in the left tail is also 0.10. Therefore, we need to find the t-value that corresponds to an area of 0.10 in the left tail with 25 degrees of freedom.

Using a t-distribution table or a calculator, we find that the t-value for an area of 0.10 in the left tail with 25 degrees of freedom is approximately -1.711.

Since the t-distribution is symmetric, the t-value for an area of 0.10 in the right tail with 25 degrees of freedom is the negative of the t-value for an area of 0.10 in the left tail. Therefore, the t-value we are looking for is approximately 1.711.

(b) Finding the t-value for an area of 0.05 in the right tail with 30 degrees of freedom:

Similar to part (a), using symmetry, we can find the t-value for an area of 0.05 in the left tail with 30 degrees of freedom.

Using a t-distribution table or a calculator, we find that the t-value for an area of 0.05 in the left tail with 30 degrees of freedom is approximately -1.699.

Again, due to symmetry, the t-value for an area of 0.05 in the right tail with 30 degrees of freedom is the negative of the t-value for an area of 0.05 in the left tail. Therefore, the t-value we are looking for is approximately 1.699.

(c) Finding the t-value for an area of 0.01 in the left tail with 18 degrees of freedom:

To find the t-value for an area of 0.01 in the left tail with 18 degrees of freedom, we can directly use a t-distribution table or a calculator.

Using a t-distribution table or a calculator, we find that the t-value for an area of 0.01 in the left tail with 18 degrees of freedom is approximately -2.898.

Since we are looking for the t-value that corresponds to the area left of it, the t-value we are looking for is approximately -2.898.
