A net force of 125 N accelerates a 25.0 kg mass. What is the resulting acceleration?

Answer: a=5 m/s^2

Explanation:

The acceleration of an object can be calculated by using Newton's second law:

F=ma

where

F is the net force applied on the object

m is the mass of the object

a is its acceleration

In this problem, we have F=125 N and m=25.0 kg, so we can rearrange the equation to calculate the acceleration:

a=\frac{F}{m}=\frac{125 N}{25.0 kg}=5 m/s^2

Please help! Find the tension in each cord in the figure if the weight of the suspended object is w = 210N A) Find the tension in the cord A for system (b). B) Find the tension in the cord B for system (b).

We have to solve the system of equations:
- T a * cos 60° + T b * sin 45° - 210 N = 0
- T a * sin 60° + Tb cos 45° =  0
------------------------------------------------------
- 1/2 T a + √2 / 2 T b = 210 N
- √3 / 2 T a + √ 2 / 2 T b = 0     / * ( - 1 )
---------------------------------------------------
- 1/2 T a + √2 / 2 T b = 210 N
√ 3 / 2 T a - √2 / 2 T b = 0
----------------------------------------
T a ( √3 / 2 - 1 / 2 ) = 210 N
0.366 T a = 210 N
T a = 210 N : 0.366
1 ) T a = 573.77 N
Ta * √3 / 2 = T b * √ 2 / 2
T b = ( 573.77 * 1.732 ) : 1.4142
2 ) T b = 702.7 N

If you increase the force on an item without changing the mass you increase acceleration? true or false?

(F)(M)=A
Force times Mass equals Acceleration.
The answer is TRUE. 
If the mass increases the number on the left side of the equation increases, thus increasing the right side as well.

A 10.00 g sample of a compound containing only carbon, hydrogen, and oxygen forms 23.98 g CO2 and 4.91 g H2O upon complete combustion. What is the empirical formula of the compound?

(23.98 g CO2) / (44.00964 g CO2/mol) × (1 mol C / 1 mol CO2) = 0.544881 mol C 
(0.544881 mol C) × (12.01078 g C/mol) = 6.54445 g C 

(4.91 g H2O) / (18.01532 g H2O/mol) × (2 mol H / 1 mol H2O) = 0.54509 mol H 
(0.54509 mol H) × (1.007947 g H/mol) = 0.54942 g H 

10 g total - 6.54445 g C - 0.54942 g H = 2.90613 g O 
(2.90613 g O) / (15.99943 g O/mol) = 0.18164 mol O 

Divide by the smallest number of moles: 
(0.544881 mol C) / 0.18164 mol = 2.9998 
(0.54509 mol H) / 0.18164 mol = 3.0009 
(0.18164 mol O) / 0.18164 mol = 1.0000 
Round to the nearest whole number to find the empirical formula: 
C3H3O

A student hangs a mass of 150 g on a force table at an angle of 150 degrees . If she then hangs a mass of 220 g at 270 degrees. A) at what angle should she hang a mass of 195 g so that the ring is in equilibrium? B) Draw the vectors

Horizontally: 150g*cos150 + 220g*cos270 + 195g*cosΘ = 0 
cosΘ = 0.666
Θ = ± 48º 
Vertically: 
150g*sin150 + 220g*sin270 + 195g*sinΘ = 0 
sinΘ = 0.744 
Θ = 48º

Which is the best reason for using a temperature probe instead of a thermometer? to make measurements in degrees Celsius to make measurements in degrees Fahrenheit to record continuous measurements over several minutes to record individual measurements several times in a day

Answer;

to record continuous measurements over several minutes

Explanation;

  • A temperature probe is a type of temperature sensor that is used to measure temperature changes.
  • Temperature probes are used in almost any industries with most common being, medical, food, communication and motor spot among others.
  • Temperature probes are advantageous and more preferred to thermometers as they record continuous measurements over several minutes. Other advantages include, greater sensitivity, could link to a computer for data analysis, reduces instrument reading error, etc.

Which of the following is the most appropriate unit to describe the rate at which water flows out through a standard household faucet? Minutes per gallon, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes. Gallons per minute, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes. Minutes per gallon, because the independent quantity is time in minutes and dependent quantity is volume of water in gallons. Gallons per minute, because the independent quantity is time in minutes and dependent quantity is volume of water in gallons.

Answer:

Gallons per minute, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes.

Explanation:

As we know that gallons is the unit of volume which is used in US to measure volume of gas as well as liquids while time is measured in minutes.

Now we know that if we need to find the volume flow rate then in that case the measurement is done to find the amount of fluid flow per unit of time

so here since volume flow is an independent variable which do not depends on any other parameter while time is a dependent variable here which is given as

flow \: rate = \frac{dV}{dt}

so correct answer will be

Gallons per minute, because the independent quantity is volume of water in gallons and dependent quantity is time in minutes.

You have to find the calculate the circumference first then you can just multiply the diameter by π, which is about 3.142. That gives you the distance for each revolution. Then you can multiply by the number of revolutions per minute.
