Answer:
The atomic number increases by 1.
Explanation:
The beta minus decay is a process in which a neutron decays into a proton, emitting an electron and an anti-neutrino:
If this process occurs inside an unstable nucleus, we notice that:
- a neutron is converted into a proton, therefore
- the number of neutrons decreases by 1 and the number of protons increases by 1
Keep in mind that the atomic number of a nucleus corresponds to the number of protons it contains: therefore, since this number increases by 1, then the atomic number increases by 1.
We convert from degrees Celsius to degrees Kelvin,
- <em>Initial Temperature</em>
- <em>Coolent Temperature</em>
Convective temperature coefficient,
For steel we have to,
Given the error equation, then
A)
At x=0
From the tables,
B)
At
At this value
Answer:
C: Variation in the value of g as the pendulum bob moves along its arc.
Explanation:
The formula for period of a simple pendulum is given by;
T = 2π√(L/g)
Where;
L is length
g is acceleration due to gravity
Now, from this period equation, it is clear that the only thing that can affect the period of a simple pendulum are changes to its length and acceleration due to gravity.
Looking at the options, the only one that talks about either the length or gravity as being potential causes of the error is option C
From definition 1 kWh = 3600000 J
The formula for KE = 1/2 * m * v^2
3600000 = 1/2 * 1000 * v^2
3600000 = 500v^2
v^2 = 7200
v = 84.85 m/s
Answer:
a) The magnitude of the car's total displacement (T) from the starting point is T = 82.67 Km
b) The angle (θ) from east of the car's total displacement measured from the starting direction is θ = 40.88 °
Explanation:
Attached you can see a diagram of the problem.
a) Find the magnitude of the vector T that goes from point A to point D (see the diagram).
The x and y components of this vector are
The magnitude of the vector is find using the pythagoras theorem:
, being a, b and c the 3 sides of the triagle that forms the vector:
Replacing the values
b) Find the angle θ that forms the vector T and the vector AB (see diagram).
To find this angle you can use the inverse tangent
θ
θ
θ=40.88°
