Two point charges are brought closer together, increasing the force between them by a factor of 17. By what factor was their sep

nignag [31]

Answer:

$\dfrac{r_1}{r_2}=4.123$

Explanation:

Given:

Final force between them=17(initial force between them)

initial separation between them $r_1$

Final separation between them $r_2$

Let Q and q be the charges on them then

$F_2=17F_1\\\dfrac{kQq}{r_2^2}=17\dfrac{kQq}{r_1^2}\\\dfrac{r_1^2}{r_2^2}=17\\\dfrac{r_1}{r_2}=4.123$

Weekend A Assignment Differentiate between forced and damped oscillation

4vir4ik [10]

Answer:

A damped oscillation means an oscillation that fades away with time while Forced oscillations occur when an oscillating system is driven by a periodic force that is external to the oscillating system.

Explanation:

Damping is the reduction in amplitude (energy loss from the system) due to overcomings of external forces like friction or air resistance and other resistive forces. ... When a body oscillates by being influenced by an external periodic force, it is called forced oscillation.

Which statement BEST compares the force of gravity on a school bus on a school day and a weekend? *

inna [77]

Answer:

(A) The force would be lower on the school day than the weekend.

Explanation:

In a school day the bus is on the road travelling with kids. But in a weekend it is parked. When a object stays still that means the the force which is working on the earth by the bus is equal to the force which works on the bus by the earth. we can understand it clearly by, Newton's second law of motion.

This pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. so as it is when it is balanced it is not moving.

And on a school day the bus is moving so it has a force pulling itself forward . so it means that the force which the bus has is greater than the gravitational force.

Binding of a signaling molecule to which type of receptor leads directly to a change in the distribution of ions on opposite sid

aalyn [17]

Binding of a signaling molecule to ligand-gated ion channel leads directly to a change in the distribution of ions on opposite sides of the membrane

Explanation:

The ligand-gated-ion-channel is trans membrane protein buildings that conduction course through the channel pores in light of the official of a neurotransmitter. They are not quite the same as voltage - gated - ion - channels, which are delicate to film possibilities, and G-protein coupled receptors (GPCR's), which utilize second messengers.

These ion channels, additionally ordinarily referred to as ionotropic receptors, are a gathering of trans membrane -ion-channel proteins which open to permit ions, for example, $N a^{+}, K^{+}$ and potentially $c l^{-}$ to go through the layer in light of the official of a synthetic errand person, for example, a neurotransmitter.

To impress his friends while riding on a carnival

s344n2d4d5 [400]

Answer:

B. decreases while his angular speed remains unchanged.

Explanation:

His angular speed will always be the same as the wheel's angular speed, which remains constant as it's in uniform motion. As for linear speed, which is defined as the product of angular speed and distance r to the center of rotation, and his distance to center is decreasing, his linear speed must be decreasing as well.
