Answer: electron microscope

Explanation:

An electron microscope is a microscope which uses an electron beam to illuminate a specimen and it creates an enlarged image of that specimen. This microscope exhibit a very high resolving power as compared to light microscopes. This is capable of obtaining very high magnification. Some of the electron microscopes can magnify an image of the specimen upto 2 million times.

The answer is the electron microscope. It is a kind of microscope that uses electrons to light a sample and make an enlarged image. These kinds of microscopes have much better determining power than light microscopes and can get much higher magnifications.

okay so i already answered this question A. what is the density of an 84.7g sample of an unknown substance if the sample occupie
Lera25 [3.4K]
The density of the substance is obtained by dividing its mass by its volume. Density is an intensive property which means that its value does not depend on the amount of substance and will always stay the same for same conditions.  
                                   d = 84.7 g / 46.7 cm³ = 7.75 g / x cm³
The value of x is approximately 4.27 cm³.

Assume that the total cholesterol levels for adults are normally distributed with mean cholesterol level of 51.6 ​mg/dL and stan
Ivahew [28]

Answer:

therefore, the probability that an individual will have a cholesterol level greater than 60 ​mg/dL.= 0.27

Explanation:

given data

Normal distribution

mean cholesterol level μ= 51.6 ​mg/dL

Standard deviation σ=  14.3 ​mg/dL

x= 60 mg/dL

We have to find out P(x>60)

We Know that P(x>a) =P(Z>(a-\mu)/\sigma)

therefore, P(x>60) =P(Z>(60-51.3)/14.3)

= P(Z>0.61)

= 1 - P(Z<0.61)

= 1 - 0.7291

= 0.27

therefore, the probability that an individual will have a cholesterol level greater than 60 ​mg/dL.= 0.27

. Calcula el módulo del vector resultante de dos vectores fuerza de 9 [N] y 12 [N] concurrentes en un punto o, cuyas direcciones
ycow [4]

Answer:

a) 20.29N

b) 19.42N

c) 15N

Explanation:

To find the magnitude of the resultant vector you can consider an axis in the middle of the vector, from which you can calculate the components of the vectors by using the angles given:

a) for 30°

F_1=[9cos(15\°)\hat{i}+9sin(15\°)\hat{j}]N\\\\F_1=[8.69\hat{i}+2.32\hat{j}]N\\\\F_2=[12cos(15\°)\hat{i}-12sin(15\°)\hat{j}]N\\\\F_2=[11.59\hat{i}-3.10\hat{j}]N\\\\F=F_1+F_2=20.28N\hat{i}-0.78N\hat{j}\\\\|F|=\sqrt{(20.28N)^2+(0.78N)^2}=20.29N

F = 20.29N

b)  for 45°

F_1=[9cos(22.5\°)\hat{i}+9sin(22.5\°)\hat{j}]N\\\\F_1=[8.31\hat{i}+3.44\hat{j}]N\\\\F_2=[12cos(22.5\°)\hat{i}-12sin(22.5\°)\hat{j}]N\\\\F_2=[11.08\hat{i}-4.59\hat{j}]N\\\\F=F_1+F_2=19.39N\hat{i}-1.15\hat{j}\\\\|F|=\sqrt{(19.39N)^2+(1.15N)^2}=19.42N

F= 19.42N

c) for 90°

for this case you can consider that the direction of both vectors are the y and x axis of the Cartesian plane:

F_1=9N\hat{i}\\\\F_2=12N\hat{j}\\\\F=\sqrt{(9N)^2+(12N)^2}=15N

F=15N
