How are Christian beliefs different than those who believe in reincarnation?
Answer:
While different religious groups like Hinduism, Sikhism, Jainism, and Buddhism belief in reincarnation and that a person has the chance to be reborn as a new person, depending on how the current life is, Christianity holds a different belief in that there is no reincarnation per se, but there is an afterlife with God for eternity in His kingdom.
Explanation:
The basic concept of reincarnation is a belief held by major religions of the world such as Hinduism, Jainism, Buddhism, and Sikhism. This philosophical belief holds that there is a rebirth or transference of an aspect of a person, be it the soul or mind or any subconscious to a different entity after one dies.
While Christianity does not specifically belief in reincarnation, it does hold the belief that the physical or bodily death of a person is not the end of that person. Rather, Christians belief in the afterlife, a life of eternity with God in His kingdom. This is not the same as reincarnation, for it involves no such rebirth as some other animal or even into a new person or being.
Thus, the Christian belief of afterlife is much different from the other religious beliefs of reincarnation.
4. Mr. Ames is dragging a box full of books from his office to his car. The box and books together have a
combined weight of 134 N. If the coefficient of static friction between the pavement and the box is 0.55, low hard
must Mr. Ames push horizontally on the box in order to start it moving?[74N]
Answer:
F = 73.7 N = 74 N (rounding off)
Explanation:
In order to get the box to start moving, Mr. Ames must push it with a force equal to the frictional force acting on it. Therefore, this force can be calculated through the following formula:
[tex]F = frictional force = \mu R[/tex]
where,
μ = coefficient of friction = 0.55
R = Normal Force on Box = Weight of Box with books = 134 N
Therefore,
[tex]F = (0.55)(134\ N)\\[/tex]
F = 73.7 N = 74 N (rounding off)
Is it possible that the physical velocity is constant but the magnitude of the velocity is variable?give an example
Answer:
yes it is possible
Explanation:
if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.
eg: a body in uniform circular motion has constant speed but its velocity changes at every point during the course of motion. Whenever, the direction changes, velcoity changes.

When 24500J of energy is supplied to a 2.0 kg block of aluminum.Its temperature rise from 20oc to 35oc.The block is well insulate so that there is no energy loss to the sorrounding Determine specific aluminum
Explanation:
Amount of heat supplied (Q) = 24500 J
Mass (m) = 2 kg
Initial temperature (t1) = 20 ° C
Final temperature (t2) = 35 ° C
Difference in temperature (dt) = t2 - t1 = ( 35 - 20) °C = 15 ° C
Now Specific heat capacity (S) = ?
We know we have the formula;
Q = m * s * dt
24500 = 2 * s * 15
24500 = 30 S
S = 24500 / 30
S = 816.67 J / Kg ° C
The specific heat capacity is 816.67 J/kg°C.

Which best describes pitch?
A) the amount of time taken for a longitudinal wave to produce one cycle
B) the number of cycles per second perceived by the human ear
C) the amplitude of a wave when the natural frequency is matched
D) the distance between two corresponding parts of a transverse wave
Answer:
B) the number of cycles per second perceived by the human ear
Explanation:
The best expression that describes pitch is that it is the number of cycles per second perceived by the human ear.
For a wave train, the number of cycles per second is frequency. Whereas the period is the amount of time taken for a longitudinal wave to produce one cycle.
The distance between two corresponding parts of a transverse wave is its wavelength.
A high pitch will correspond to a high frequency of waves perceived. A low pitch corresponds to a low frequency of waves.The current shape of the solar system is *

What is the force of gravitational attraction between an object with a mass of 2kg and another that has a mass of 2kg and a distance between them of 2.5 m
Answer:
Explanation:
F = 0.000000000042716 or 4.2688e-11
G = 6.67 × 10−11 Nm2 /kg2
m1 = 2kg
m2 = 2kg
R = 2.5 m ⇒ R^2 = 6.25
F = 6.67 × 10^−11 ( 2 * 2) / 6.25
⇒ F = 6.67 × 10^−11 (4) / 6.25
⇒ F = 2.668e-10 / 6.25
∴ F = 4.2688e-11
A worker for a moving company is pushing on a refrigerate with a force of 1500 Newtons but the refrigerator just won’t move. How much work did the worker do on the refrigerator?
Answer:
0 J
Explanation:
Work is the product of force applied and the distance moved by the object.
In this case, the force applied on the refrigerator is 1500 N
The refrigerator did not move, thus no distance , hence distance is zero
The formula for work done:
W = F*d
W= 1500 * 0
W= 0 J

At a depth of 1030 m in Lake Baikal (a fresh water lake in Siberia), the pressure has increased by 100 atmospheres (to about 107 N/m2). By what volume has 1.0 m3 of water from the surface of the lake been compressed if it is forced down to this depth
Answer:
the volume that has 1.0m^2 of water from the surface of the lake is 4.3
Explanation:
The computation of the volume is as follows;
The Bulk modulus is
= K = 2.3 × 10^9 Pa
K = - V dP ÷ dV
dV = - V dP ÷ K
dV = - (1 × 101.3 × 1000) ÷ 2.3 × 10^9
= - 4.3 × 10^-3 m^3
So the volume that has 1.0m^2 of water from the surface of the lake is 4.3

A naked, male corpse was found at 8AM on Tuesday, July 9.The air temperature wasalready 26.7˚C (81˚F). The body exhibited some stiffness in the face and eyelids and had a body temperature of 34.4˚C (93.9˚F). Livor mortis was not evident. Approximately how long ago did the man die? Justify your answer. Would clothing on the body have made a difference in determining the actual time of death in this case? Why or why not?
Answer:
x = 9.87 hours ago.
Further explanation is present below.
Explanation:
Data given:
Air Temperature = 26.7°C (81°F)
Body temperature = 34.4°C (93.9°F)
We are given that, Livor mortis was absent. Secondly, The body exhibited some stiffness in the face and eyelids.
So, it can be concluded that, body must have died recently, as Livor mortis was absent plus the presence of stiffness in the face and eyelids. Furthermore,
The normal body temperature = 37°C
Body temperature in our case = 34.4° C
Difference = 37 -34.4 = 2.6°C
And Air temperature = 26.7°C
Which is a very low difference, in addition, it has not acquired the air temperature so, all this evidence certifies that body died recently.
Now, we have to calculate, how recently it died.
Formula:
0.78 . x = difference of body temperature and air temperature
Where, x = number of hours = time required,
0.78 . x = (34.4 - 26.7)
0.78 . x = 7.7
x = 7.7/0.78
x = 9.87 hours ago.
It means that, naked male corpse was died 9.87 hours ago.
Now, we are asked to find out clothing on the body had made a difference or not.
So, Yes it would definitely make a difference. As body would have more warmer than being naked. and it would result in a calculation of a different time of death. (body temperature would have > 34.4°C)
Two astronauts, A and B, both with mass of 60Kg, are moving along a straight line in the same direction in a weightless spaceship. Relative to the spaceship the speed of A is 2 m/s and that of B is 1 m/s. A is carrying a bag of mass 5 Kg with him. To avoid collision with B A throws the bag with a speed v relative to the spaceship towards B catches it. Find the minimum value of v.
Answer:
[tex]V=14m/s[/tex]
Explanation:
From the Question we are told that
Mass of A and B is 60kg
Speed of A=2m/s
Speed of B=1m/s
Mass of bag =5kg
Generally the momentum of the astronaut A and bag is mathematically given as
[tex]M_A=(60+5)*2[/tex]
[tex]M_A=130kgm/s[/tex]
Generally to avoid collision the speed of astronaut be should be less than or equal to that of astronaut A with the bag
Therefore for minimum requirement speed of astronaut A should be given by astronaut B's speed which is equal to 1
Therefore
[tex]130=(60*1)=(5*v)[/tex]
[tex]V=14m/s[/tex]
To avoid collision with B, A throws the bag with a speed of 26 m/sec.
Given-
The mass of the two astronauts A and B is 60 kg.
The mass of astronaut A is 65 kg with the box.
The speed of astronaut A is 2 m/sec.
The speed of astronaut B is 1 m/sec.
The mass of the bag is 5 kg.
The momentum of a body is the product of its mass and velocity. Thus the momentum of astronaut A is,
[tex]M_{A} =m_{a} \times v_{a}[/tex]
[tex]M_{A} =(60+5)\times2[/tex]
[tex]M_{A} =130[/tex]
To avoid the collision with B, A throws the bag with a speed v. For this the momentum after the trough must be equal to the momentum of A. Therefore,
[tex]M_{A} =5\times v_{r}[/tex]
[tex]130 =5\times v_{r}[/tex]
[tex]v_{r}= \dfrac{130}{5}[/tex]
[tex]v_{r}=26[/tex]
Hence, to avoid collision with B, A throws the bag with a speed of 26 m/sec.
