If the activity of a source is 70 Bq after 2 years, and 35 Bq after 15 years. How long will be until the activity is 8.75 Bq?
Answer:
N = N0 e^-kt calling k the decay constant
70 = N0 e^-2 kt
35 = N0 e^-15 k
2 = e^(-2 + 15) k
.693 = 13 k
k = .0533
N0 = N e^kt
N0 = 70 e^(.0533 * 2) = 77.87
8.75 = 77.87 e^-(.0533 t)
ln .1124 = -.0533 t
t = -ln .1124 / .0533 = 41 yr
Zeb was lifting a box onto a moving truck. He lifted with a net force of 2000N and the box had a mass of 100 kg. What was the resulting acceleration?
Answer:
20 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{2000}{100} = 20 \\ [/tex]
We have the final answer as
20 m/s²Hope this helps you

The gravitational field on Saturn is 10.4 times its value on Earth.
a. What would a 100.0-kg mass weigh on Saturn?
b. If the gravitational field on the surface of Pluto is 0.08 times that of Mercury, what would a 7.0-kg mass weigh on Pluto?
Show all work!!
The weight of 100 kg mass on Saturn is 10,192 N.
The weight of 7.0 kg mass on Pluto is 2.01 N.
The given parameters;
acceleration due to gravity, = 10.4gmass of the Saturn, m = 100 kgacceleration due to gravity on mercury, = 3.59 m/s²The weight of 100 kg mass on Saturn is calculated as follows;
W = mg
W = 100 x 10.4 x 9.8
W = 10,192 N
The weight of 7.0 kg mass on Pluto is calculated as follows;

Explain this phase diagram by relating what you know about temperature, states of matter and
pressure.
Answer:
See explanation
Explanation:
The vertical axis corresponds to the pressure of a substance, while the horizontal axis corresponds to the temperature. The solid is the substance which contains particles of strong intermolecular force and compaction, typically ionic at a certain temperature, the liquid is the substance which contains relatively compact molecules, however lacks a particular arrangement. The gaseous substance is caused by particles with weak intermolecular forces, causing particle movement and collision with no arrangement whatsoever. The triple point as shown in the diagram, is the phrase on a diagram where each substance: solid, liquid and gas coexist. The critical point is the phase at which the/a substance is indistinguishable between liquid and gaseous states. A substance or elements state is highly dependent on its environment and it’s temperature, of which ultimately affects its kinetic energy within its particles. This is what the graph portrays and represents.

Answer:
3 times as much
Explanation:
half as much would be 12%, as much would be 24%, and two times as much would be 48%.
3 times as much is 72, which is about 74%
How is temperature related to the physical change of a substance
Answer:
Temperature is a measure of the kinetic energy of particles in a substance. As temperature increases, the atoms or molecules in a substance gain energy. As temperature decreases, the particles lose energy. A change in the energy of particles causes a change in their arrangement. A change in the arrangement of particles can lead to a physical change.

Which statement is true about vectors?
Vectors need direction and magnitude to exist, otherwise, it becomes scalars that do not require direction to be expressed.
eg - Velocity is a vector as it needs direction, but speed is scalar and does not need direction
hope this helps
Answer:
a. All quantities in physics are not vectors. b. A vector may have either magnitude or direction. c. The vector's length should be proportional to its magnitude. d. Two vectors can be added only if they have the same direction.

what is the mass on mercury of an object that weighs 784 n on the earth’s surface?
Answer:
80 kg weighs 80 kg x 9.8 m/s2 = 784 kg m/s2, or 784 Newtons. The surface gravity of Mercury is 0.39 that of Earth's (table 10-1), so 80 kg weighs 784 N x 0.39 = 306 N.

In the absence of friction, explain why the horizontal component of a projectile’s velocity is a constant.
Answer:
This downward force and acceleration results in a downward displacement from the position that the object would be if there were no gravity. The force of gravity does not affect the horizontal component of motion; a projectile maintains a constant horizontal velocity since there are no horizontal forces acting upon it
NEED ANSWER FAST
A person pushes a 11.5KG lawn mower with an applied force of 70.0N along the 45.0-degree-handle. if the lawn mower moves at a constant velocity
Determine the net force on the mower:
Fnet=__N
Determine the horizontal component of applied force on the mower:
Fx=__N (round to 3 digits)
Determine the horizontal frictional force acting on the mower
Ff=__N (Round to 3 digits)
Calculate the applied force the person must exert on the mower for it to accelerate at a rate of 1.00m/s^2
F=__N (round to 3 digits)
Force is a vector quantity hence it can be resolved into a vertical and a horizontal components.
1) The horizontal component of the applied force is given by;
Fnet = F cos θ
Fnet = 70.0N × cos (45.0)
Fnet = 49.5 N
2) The horizontal component of the frictional force is;
F = -Ff + mgsinθ
F = applied force
Ff =mgsinθ - F
Ff = (11 × 10 × sin 45) - 49.5
Ff = 28.3 N
Horizontal component of Ff
28.3 N cos 45 = 19.9 N
3) The applied force is given by;
F = 11 Kg × 1.00m/s^2 = 11.0 N
