A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed.
O A. 0.12 m/s
OB. 1.1 m/s
O c. 2.4 m/s
OD. 3.6 m/s

Answers

Answer:

The answer is option D

Explanation:

To find the speed given the kinetic energy and mass we use the formula

[tex]v = \sqrt{ \frac{2KE}{m} } \\ [/tex]

where

m is the mass

v is the speed

From the question

KE = 15 J

m = 2.3 kg

We have

[tex]v = \sqrt{ \frac{2 \times 15}{2.3} } = \sqrt{ \frac{30}{2.3} } \\ = 3.61157559...[/tex]

We have the final answer as

3.6 m/s

AgF (aq) + KNO3 (aq) →

Answers

Answer:

AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)

Explanation:

AgF (aq) + KNO₃ (aq) →

The products from the equation above can be obtained as follow:

1. AgF and KNO₃ will dissociate in solution as shown below:

AgF (aq) —> Ag⁺(aq) + F¯(aq)

KNO₃ (aq) → K⁺(aq) + NO₃¯(aq)

2. A double displacement reaction will occur between AgF and KNO₃ as illustrated below:

AgF (aq) + KNO₃ (aq) →

Ag⁺(aq) + F¯(aq) + K⁺(aq) + NO₃¯(aq) → Ag⁺NO₃¯(aq) + K⁺F¯(aq)

AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)

A careful observation of the above equation shows that the equation is balanced.

Autism is a disability that results from a disorder in the central nervous system. It has been speculated that the increasing number of cases of autism in recent years is due to the increase in the number of vaccinations given to young children. What might be another possible explanation for this phenomenon?

Answers

Answer:

Explanation:

As described in the question, autism is a disability that arises from a disorder in the central nervous system which is actually characterized by abnormality in the brain structure and then function. Autism is known for symptoms such as challenges with communication and interaction and some obsessive behaviors. While there is generally no known scientific cause for autism but trends have suggested that vaccination in young children causes autism.

However, genes could also be involved in this phenomenon because there have been reports of unusual genetic sequence in children that have autism. Hence, there is a possibility that vaccination actually triggers this genetic sequence which is then expressed as autism in the children.

Please note this isn't a scientific fact and just a possibility as requested in the question.

In each of the following pairs, circle the form of radiation with the LONGER WAVELENGTH:

A. red light or blue light

B. microwaves or radiowaves

C. infrared radiation or red light

D. gamma rays or UV rays​

Answers

Answer:

In the first one in a it is red light in b it is radio waves in c it is infrared radiation and d is UV radiation

Explanation:

The forms of radiation from the pairs listed that have longer wavelength are :

A) Red light

B) Radio waves

C) Infrared radiation

D) UV rays

Red light have a wavelength between 650 to 720 nm while a Blue light has a wavelength of 380nm to 500nm which makes it to produce a high energy  visible light.( HEV ) light. therefore the Red light has a longer wavelength.

The wavelength of a microwave is approximately  30 centimeters to 1 millimeter, which makes it shorter than the wavelength of a radio wave ( shortest wavelength in the electromagnetic spectrum.

Hence we can conclude that The forms of radiation from the pairs listed that have longer wavelength are A) Red light B) Radio waves C) Infrared radiation D) UV rays
