A bare helium nucleus has two positive charges and a mass of 6.64 ✕ 10−27 kg.

Answer:

Explanation:

The net force on the man is the sum of all the forces acting on him. In this case, the only force acting on the man is the force of gravity, which is given by:

F = m*g

= 75 kg * 9.8 m/s^2

= 735 N

where m is the mass of the man, g is the acceleration due to gravity, and F is the force of gravity.

Since the man is motionless, the net force on him must be zero. Therefore, the tension in the cord must be equal and opposite to the force of gravity:

T = -F

= -735 N

The tension in the cord is therefore T = -735 N. The negative sign indicates that the tension is directed downward, opposite to the direction of the force of gravity.

Net Force on Man = 735 N (downward)

Tension in Cord = 735 N (upward)

Explanation: The net force on the man is equal to his weight (75 kg x 9.81 m/s2 = 735.75 N).

This force is directed downward. To keep the man in equilibrium, the tension in the cord must be equal in magnitude, but opposite in direction, so the tension is also 735.75 N, but directed upward.

The force that q₂ exerts on q₁ at this new location is 1.44 µN  in  - X axis direction.

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. A spring balance can be used to calculate the Force. Newton is the SI unit of force.

As electric force due to point charge is inversely proportional to the square of distance.

Given that with q₁ at the origin and q₂ initially at x₁ = 13.2 mm,  q₁ exerts a repulsive force of 2.62 µN on q₂.

Hence,  with q₁ at the origin and q₂ initially at x₁ = 17.8 mm,  q₁ exerts a repulsive force of on q₂ = 2.62 µN (13.2/17.8)²

=  1.44 µN .

So, q₂ exerts a force of  1.44 µN on q₁ at this new location in - X axis direction.

According to Doerbecker and Ernst (1996) and Francart et al. (2011), interaural time difference (ITD) and interaural level difference (ILD) are the two primary auditory cues used by binaural hearing. The delay between each ear is known as ITD.

What technique best localizes sound between the two ears?

Rayleigh's view of horizontal sound localization has come to be known as the “duplex” theory: that sound localization at low frequencies relies on differences in phase at the two ears, or ITDs, and that high-frequency localization relies on interaural differences in sound level (ILDs).

What two variables affect sound localization?

The variation in the loudness of the sound in each ear and the time it took for the sound to reach each ear are two elements that affect how the sound is localized.

n unit vector notation, -22j is the torque about the origin on a particle located at coordinate (o, -4.0m, 3.0m)


Torque is defined as the force that can cause an object to rotate along an axis is measured as torque. Estimate the angle between the vector connecting the force's application point and the pivot point and the direction of the applied force. You may calculate the torque by multiplying r by F and sin.

T=R (distance) x F (Force)

R=-4j+3k

F=2J

Hence, t=  R x F vector product

=(-4j+3k)x2j

=-4x2x(y x J)

=+3x2y(k x r)

=-8x(-k)+6j

=(6j+8k) nm

b) F^2=2J+4K

Hence, t=r x f^2

Answer:

One thing that is demonstrated by plotting the results of IQ tests on a bell curve is that most scores fall in the middle of the curve, with fewer scores outside the curve. This reflects the fact that IQ scores are typically distributed in a normal or bell-shaped curve, with most scores falling around the average, and fewer scores falling at the very high or very low ends of the distribution. The bell curve is a useful tool for visualizing the distribution of IQ scores, and it can help researchers and psychologists understand the typical range of scores and identify any unusual patterns or outliers. It is not accurate to say that most scores are above average or below average, or that there is a large difference between the scores of women and men. These statements do not accurately reflect the findings of IQ tests or the use of the bell curve to analyze their results.

Answer:

It is most likely that the score on the second test should be close to 130 as IQ is a steady measurement. Intelligence quotient (IQ) is a measure of a person's cognitive ability and is typically considered to be a stable trait that does not change significantly over time. While some research has suggested that certain aspects of cognitive ability may improve with age, the overall IQ score is generally considered to be a consistent measure of cognitive ability. Therefore, it is unlikely that Juanita's score on the second test would be significantly different from her score on the first test.

A piston has a volume change of 7 x 10^-6 m^3. Assuming atmospheric pressure is 101,325 Pa, what is the work needed to change the piston volume?

Answer:

The work needed to change the piston volume is 0.709 J

Explanation:

Given;

volume of the piston, V = 7 x 10⁻⁶ m³

atmospheric pressure, P = 101,325 Pa

The work needed to change the piston volume is calculated as follows;

W = (7 x 10⁻⁶ m³) x (101,325 Pa)

W = 0.709 J

Therefore, the work needed to change the piston volume is 0.709 J

The magnitude of the force of the roller-coaster track on the bottom of each clip can be ranked from largest to smallest as follows: R = 50 m, speed = 10 m/s R = 100 m, speed = 10 m/s R = 50 m, speed = 5 m/s.

The magnitude of the force of the roller-coaster track on the bottom of a clip is determined by the radius of curvature of the track and the speed of the clip.

For a given radius of curvature and speed, the magnitude of the force will be larger when the radius of curvature is smaller and the speed is larger, and smaller when the radius of curvature is larger and the speed is smaller.

Based on this information, the magnitude of the force of the roller-coaster track on the bottom of each clip can be ranked as follows:

R = 50 m, speed = 10 m/s

R = 100 m, speed = 10 m/s

R = 50 m, speed = 5 m/s

The magnitude of the force of the roller-coaster track on the bottom of the clip with a radius of curvature of 50 m and a speed of 10 m/s will be the largest. The magnitude of the force of the roller-coaster track on the bottom of the clip with a radius of curvature of 100 m and a speed of 10 m/s will be smaller.

If a wavelength of a wave increases, but the wave speed remained the same, the frequency will decrease (option B).

Wavelength is the length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next.

The wavelength is often designated in physics as λ, and corresponds to the velocity of the wave divided by its frequency as follows:

λ = v/f

According to the above equation, the wavelength is inversely proportional to the frequency of the wave, hence, as one increases, the other decreases and vice versa.
