Explanation: The amount of solar energy available varies by location on earth, the time of the day at that location, the season and weather conditions. Rain, fog, and clouds will lower the amount of solar power available to gather and there are fewer hours of sun available in different seasons (winter for North America). To gather solar power, you also need a large area. This can be lessened by conditions such as snow, so that even on a sunny day, covered panels will collect less energy.
Answer:
.
Explanation:
The quantity of solar energy accessible varies by location on the planet, time of day, season, and weather conditions. Rain, fog, and clouds reduce the quantity of solar power available for collection, and various seasons have less hours of sunlight accessible (winter for North America). A big region is also required to collect solar electricity. Conditions such as snow can reduce this, such that even on a sunny day, covered panels will absorb less energy.
A student slides a box across the floor to his friend. The mass of the box is 25 kg and the
coefficient of kinetic friction between the floor and the box is 0.52. If the initial velocity
of the box is 7.0 m/s, how far will the box slide before it stops?
The distance traveled by the box before stopping, when the student slides the box across the floor to his friend, at the given coefficient of kinetic friction is 4.8 m.
Acceleration of the boxThe acceleration of the box across the floor is determined by applying Newton's second law of motion.
∑F = ma
-Ff = ma
-μmg = ma
-μg = a
-(0.52 x 9.8) = a
- 5.1 m/s² = a
Distance traveled by the box before stoppingThe distance traveled by the box before it stops is calculated as follows;
v² = u² + 2as
where;
v is the final velocity of the box when it stops = 00 = (7)² + 2(-5.1)s
0 = 49 - 10.2s
10.2s = 49
s = 49/10.2
s = 4.8 m
Thus, the distance traveled by the box before it stops is 4.8 m.

The electromagnetic spectrum consists of :
Radio wavesMicro wavesInfared wavesVisible light wavesUV raysX-raysGamma raysDue to the cylindrical symmetry of this problem, the induced electric field E⃗ (R,t) can depend only on the distance R from the z axis, where R is restricted to the region outside the iron rod. Find this field. Express E⃗ (R,t) in terms of quantities given in the introduction (and constants), using the unit vectors in the cylindrical coordinate system, θ^, r^, and k^
It is to be noted that the electric field that has been induced is (-B₁ A/2[tex]\pi[/tex]R)θ. This is obtained by using the vector units in the Cylindrical Coordinate System.
What are Cylindrical Coordinates?Cylindrical Coordinates are simply defined as a component of a coordinate system that is used to locate a location in space using its polar coordinates and vertical distance from the polar plane.
How is the induced field arrived at?The formula for Induced Electric Field is given as:
∫ E · dl = ∈
If we replace ∈ with -B₁A and 2[tex]\pi[/tex]R for dl then
∫ E · dl = -B₁A. Thus, we can state that
E∫ dl = -B₁A
Replacing or substituting 2[tex]\pi[/tex]R for ∫ dl ·E(2πR) = - B₁A
We can thus rearrange the equation to read:
E · E = ([tex]\frac{-B1A}{2\pi R}[/tex])θ
It is to be noted that the circumference of a circle is the integral of the length of the element. While θ, which in this case is the unit vector refers to the Cylindrical Coordinate and the direction of the electric field.

Describe the difference between continuous reinforcement and intermittent reinforcement.
Answer:
Continuous reinforcement delivers the reinforcement every single time the target behavior is delivered. (For example, if the target behavior for the dog is sitting when the owner says "sit", the treat (reinforcement) would be given whenever the dog follows the command). It follows a schedule-like reinforcement.
Intermittent reinforcement delivers the reinforcement to responses but are not consistent.

Answer:
The conditions for life are extremely specific and the search is extremely broad.
Explanation:
in order to sustain life, the planet has to have water.
Too hot and the water will evaporate too cold and the water will freeze, this is based on the planet's distance from the sun and its solar mass. (The mass compared to our sun) If the solar mass is double that of our sun then the planet would have to be double the distance from the sun in order to sustain life and keep the water from evaporating.

Water flows through a pipe of diameter 8.00 cm at 45.0 m/min. Find the flow rate (a) in m3 /min and (b) in L/s.
The flow rates of water through the pipe illustrates how the water flows through the pipe, and the flow rates are (a) 0.23 m³/min and (b) 3.77 L/s
The flow rate of water in m³/minThe given parameters are:
Diameter, d = 8.00 cmVelocity, v = 45.0 m/minExpress the unit of the diameter as meters (m)
d = 8.00 * 0.01 m
d = 0.08 m
The area is then calculated using:
A = π(d/2)²
So, we have:
A = 3.14 * (0.08/2)²
Evaluate
A = 0.005024 m²
The flow rate (Q) is then calculated using:
Q = A * v
This gives
Q = 0.005024 m² * 45.0 m/min
Evaluate
Q = 0.22608 m³/min
Approximate
Q = 0.23 m³/min
Hence, the water flow rate is 0.23 m³/min
The flow rate of water in L/sIn (a), we have:
Q = 0.22608 m³/min
Convert minutes to seconds
Q = 0.22608 m³/(60 s)
Divide
Q = 0.003768 m³/s
Convert m³ to L
Q = 0.003768 * 1000 L/s
Evaluate the product
Q = 3.768 L/s
Approximate
Q = 3.77 L/s
Hence, the water flow rate is 3.77 L/s

100.0 grams of an isotope with a half-life of 36.0
hours is present at time zero. How much time will
have elapsed when 5.00 grams remains?
Answer:
155.6 hrs
Explanation:
5 = 100 (1/2)^n n = 4.32 half lives
4.32 * 36 = 155.6 hrs
The required, 155.58 hours will have elapsed when 5.00 grams of the isotope remains.
What is the half-life of the element?The half-life of the element is defined as the time span in which the element grows or decays half of its whole composition of growth and decay.
Here,
The decay of a radioactive substance can be modeled by the following equation,
[tex]N(t) = N_o (1/2)^{t/T}[/tex]
where N₀ is the initial quantity of the substance, N(t) is the quantity remaining after time t has elapsed, and T is the half-life of the substance.
In this problem, we are given,
N₀ = 100.0 g
N(t) = 5.00 g
T = 36.0 hours
We want to find the time t that has elapsed. Rearranging the equation above, we can solve for t,
t = T (log N₀ - log N(t)) / log 2
Substituting the given values, we get,
t = 36.0 hours x (log 100.0 - log 5.00 ) / log 2
t = 36.0 hours x 4.643 / 0.693
t = 155.58 hours
Therefore, approximately 155.58 hours will have elapsed when 5.00 grams of the isotope remains.
