Given the information in the velocity vs. time graph, what is the displacement of the object after 1 second?

Answer:

a) 6.4 x 10^-12 cm^3

b) 17 x 10^-6 mm^2

Explanation

a). The shape is assumed to be spherical The volume = volume of a sphere = \frac{4}{3} \pi r^3

= 6.3715 μm^3

1 μm^3 = 10^-12 cm^3

6.3715 μm^3 = 6.3715 x 10^-12 cm^3

==> 6.4 x 10^-12 cm^3

Answer:

See below

Explanation:

Volume of a sphere = 4/3 pi r^3

   we are given diameter   r = 1/2 dia = 1.45 u-meter = 1.45 x 10^-4 cm

  4/3  pi (1.45 x 10^-4)^3 = 1.277 x 10^-11   cm^3    = VOLUME

1.45 u-meter = .00145 mm

Surface area = 4 pi r^2 =  4 pi (1.45 x 10^-3 ) ^2 = 2.64 x 10^-5 mm^2

The stages of the baby birth are Dilation, strong contractions, and delivery of the baby and the placenta.

Dilation, intense contractions, and delivery of the baby and placenta are the phases of a baby's birth.

The stages of the birth process are as follows;

1. The first stage includes the latent phase, in which cervical dilation begins (3 to 5 cm) along with mild contractions, and the active phase, in which strong contractions occur along with complete or nearly complete dilation.

2. The second stage is fetus expulsion or delivery, in which the cervix is fully dilated, and the baby is born.

3. The third stage is placenta delivery or expulsion, which occurs as the placenta is delivered.

4. Dilation, intense contractions, and delivery of the baby and placenta are the phases of labor and delivery.

Hence,the stages of the baby birth are Dilation, strong contractions, and delivery of the baby and the placenta.

Answer:

When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon)

A photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by. E=hf=hcλ(energy of a photon) E = h f = h c λ (energy of a photon) , where E is the energy of a single photon and c is the speed of light.

Answer:

Explanation:

yes object can move through a distance  and can have zero displacement  

as displacement is the shortest distance between two points eg: if a person has moved a distance of 20 m and comes back to his original place by moving back 20m in such a case  distance moved by the person is 40m but his displacement is 0 as shortest distance covered by him is 0 as he is in his original place

Yes, it is possible for a body to have traveled a distance yet have a displacement of zero.

Distance traveled by a body is the length of the path covered by it.

On the other hand displacement of a body is the shortest distance between the initial and the final point of a body.

When a body is traveling such that it ends at the point from where it started its journey, it covers a distance but the displacement of the body is zero.

So a body that has moved through a distance can have zero displacement.

The charge distribute on the inner surface with the radius r₁ will be zero,In the region r₁<r<r₂  will also zero. While on the outer surface with radius r₂ will be -q.

The total electric flux out of a closed surface is equal to the charge contained divided by the permittivity,

According to Gauss Law. the electric flux in a given area is calculated by multiplying the electric field by the area of the surface projected in a plane perpendicular to the field.

From the Gauss law, it is stated that the field inside the conductor is zero. Charge will lie only on the surface.

(a)The charge distribute on the inner surface with the radius r₁ will be zero.

(b) In the region r₁<r<r₂  will also zero.

(c)The outer surface with radius r₂ charge distribution  will be -q.

Hence, the charge distribute on the inner surface with the radius r₁ will be zero,

A) The stomach breaks down the food and passes it to the small intestine to be digested further.

Explanation:

I am pretty sure it is the first option because there is no way the stuff you eat can be turned into a liquid, it wouldn't make sense for the stomach to pass the digested food from small intestine to large intestine, so it would have to be the first one. A out of all of the options makes more sense and the stomach has to pass the digested food somewhere.

Explanation:

4.246 light years

The closest star, Proxima Centauri, is 4.24 light-years away. A light-year is 9.44 trillion km, or 5.88 trillion miles. That is an incredibly large distance. Walking to Proxima Centauri would take 950 million years.

Answer:

4.25 light years

Explanation:

a light year is the distance light travels in one year it is equal to 9.461 x 1012 km. alpha centauri A & B are roughly 4.35 light years away from us. proxima centauri is slightly closer at 4.25 light years.

The magnitude of the frictional force opposing the applied force is 50 N.

The friction is caused due to the relative motion between two uneven contacting surfaces.

Given is the mass of trunk m = 20kg, kinetic coefficient of friction μ = 0.255.

The normal force acting on the trunk N = mg

N = 20 kg x 9.81m /s²

N = 196.2 Newton

The friction force is

f =μN

f = 0.255 x 196.2

f =50.031 N

Thus, the  magnitude of the frictional force opposing the applied force is approximately 50N.

Explanation:

Radiation transfers thermal energy without need for contact, where areas with higher thermal energy (hot) transfer energy to areas with lower thermal energy (cold)

If the angle between their initial directions was 90 ∘ , their speed after the collision will be 4.35 m/s.

When two moving bodies after colliding stick to each other and move together is called the inelastic collision.

In inelastic collision , momentum is remains conserved.

Initial momentum =Final momentum

m₁u₁ +m₂u₂ = (m₁ +m₂ )v

where, u₁ and u₂ represents initial velocities of two hockey players and v₁ and v₂ shows the final velocities.

m₁ =m₂ =m and u₁ = u₂ =u

Substitute the values from the question, we get

2mu = 2mv

u =v

u = v x cos (θ/2)

u = 6.15 cos(90/2)

u = v = 4.35 m/s

Thus, the speed after collision is 4.35 m/s.
