Answer:

The answer to this question is given below in this explanation section.

Explanation:

            "What element has conductivity,shiney luster,magnetic

-science"

silicon has a shiny luster,But it is brittle and conducts electricity poorly.Some metalloids change their characteristics when they react with different elements.Luster conductivity and malleability are physical properties can be observed be observed without attempting to change the identity of the substance.The term physical property is an observable characteristics of a substance. in this case the luster conductivity and malleability of metals are the properties, which can be observed  by our senses.It differs from chemical properties which can only be observed when the substance change its chemical identity.

Metal are solid at room temperature with the exception of mercury which is liquid at room temperature.Luster metal have the quality of reflection light from its surface and can be polished e.g gold,silver and copper.

Answer:

Option B

a=19 m/s^{2}

Explanation:

Given information

Radius of container, r=12cm=12/100=0.12m

Angular velocity= 2 rev/s, converted to rad/s we multiply by 2π

Angular velocity, \omega=2*2\pi =12.56637061

We know that speed, v=r\omega

Centripetal acceleration, a=\frac {v^{2}}{r} and substituting v=r\omega we obtain that

a=r\omega^{2}

Substituting \omega for 12.56637061  and r for 0.12

a=0.12*(12.56637061)^{2}=18.94964045 m/s^{2}

Rounded off, a=19 m/s^{2}

A 7950-kg railroad car travels alone on a level frictionless track with a constant speed of 15.0 m/s . A 2950-kg load, initially
Alchen [17]

The new speed of car is 10.9 m/s

<h3 />

According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.

Mass of the railroad car, m₁ = 7950 kg

Mass of the load, m₂ = 2950 kg

It can be assumed as the speed of the car, u₁ = 15 m/s

Initially, it is at rest, u₂ = 0

Let v is the speed of the car. It can be calculated using the conservation of momentum as :

m_1u_1 + m_2u_2 = (m_1 + m_2) v

v =\frac{m_1u_1}{m_1+m_2}

v = \frac{7950*15}{7950+2950}

v= 10.9 m/s

Therefore, the new speed of care is 10.9 m/s

Which of the following statements about the impact of biotechnology on the environment is not true?
Vladimir79 [104]

E)  Biotechnology use can lead to an increase in soil erosion and pollution runoff through decreased pesticide use.

Explanation:

Biotechnology use cannot lead to an increase in soil erosion and pollution runoff through decreased pesticide use.

There is no relationship between biotechnology use and increase soil erosion and pollution run off.

Biotechnology involves the application of technology based on living things.
