Answer:
24) W = 75 [J]; 25) W = 1794[J]; 26) n = 8.8 (times) or 9 (times)
Explanation:
24) This problem can be solved by means of the following equation.
where:
DU = internal energy difference [J]
Q = Heat transfer [J]
W = work [J]
Since there are no temperature changes the internal energy change is equal to zero
DU = 0
therefore:
The work is equal to the heat transfered, W = 75 [J].
25) The heat transfer can be calculated by means of the following equation.
Q = 0.4*897*5 = 1794[J]
Work is equal to heat transfer, W = 1794[J]
26) Each time the bag falls the potential energy is transformed into heat energy, which is released into the environment. In this way the potential energy is equal to the developed heat.
where:
m = mass = 0.5[kg]
g = gravity = 9.81[m/s^2]
h = 1.5 [m]
The heat developed can be calculated by means of the following equation.
The number of times will be calculated as follows
n = 65/7.36
n = 8.8 (times) or 9 (times)
Answer:
Interface
Explanation:
This is a classic example of Interface technology.
An interface allows different software packages to communicate without re-entering data.
Here in this case also systems are able to communicate with one another without duplicating data entry. For example, practice management software and another for their electronic health record.
By using an electric field, it is feasible to differentiate between these different forms of radiation.
<h3>What is a radioactive source?</h3>
A source that emits radiation like gamma, beta, and alpha rays is said to be radioactive. Using an electric field, we can discriminate between these different forms of radiation.
The field does not deflate the gamma rays, but it does deflate the alpha and beta rays, with the alpha being deflated to the field's negative portion and the beta to its positive part.
Hence, by using an electric field, it is feasible to differentiate between these different forms of radiation.

Answer:
9.31%
Explanation:
We are given that
Mass of KBr=49.3 g
Volume of solution=473 mL
Density of solution =1.12g/mL
We have to find the mass% of KBr.
Mass =
Using the formula
Mass of solution=
Mass % of KBr=
Mass % of KBr=
Mass % of KBr=9.31%
Hence, the mass% of KBr=9.31%
Answer:
Coefficient of static friction will be equal to 0.642
Explanation:
We have given acceleration
Acceleration due to gravity
We have to find the coefficient of static friction between truck and a cabinet will
We know that acceleration is equal to , here is coefficient of static friction and g is acceleration due to gravity
So
So coefficient of static friction will be equal to 0.642
