Answer:
The final speed of bicycle would be 27 m/s².
Step-by-step explanation:
Given :
[tex]\small\red\bull[/tex] Initial velocity (u) = 15 m/s[tex]\small\red\bull[/tex] Acceleration (a) = 3.0 m/s²[tex]\small\red\bull[/tex] Time = 4 secondsTo Find :
[tex]\small\red\bull[/tex] Final velocity (v)Using Formula :
[tex]\longrightarrow{\pmb{\sf{v = u + at}}}[/tex]
[tex]\small\blue\star[/tex] v = final velocity [tex]\small\blue\star[/tex] u = initial velocity [tex]\small\blue\star[/tex] a = acceleration [tex]\small\blue\star[/tex] t = time takenSolution :
Substituting the values in the formula to find the final velocity :
[tex]\longrightarrow{\sf{v = u + at}}[/tex]
[tex]\longrightarrow{\sf{v = 15 + (3.0 \times 4)}}[/tex]
[tex]\longrightarrow{\sf{v = 15 + (3 \times 4)}}[/tex]
[tex]\longrightarrow{\sf{v = 15 +(12)}}[/tex]
[tex]\longrightarrow{\sf{v = 15 +12}}[/tex]
[tex]\longrightarrow{\sf{v = 27 \: {m/s}^{2}}}[/tex]
[tex]\star{\underline{\boxed{\red{\sf{v = 27 \: {m/s}^{2}}}}}}[/tex]
Hence, the final speed of bicycle would be 27 m/s².

Which is a type of heat transfer that causes the air at the top floor.
Explanation:
Convection is the the transfer of heat my the physical movement of hot masses of air. As air is heated, it expands (as do all objects). As it expands, it becomes lighter then the surrounding air and it rises.
Quantities that can be described completely by their magnitude or size are called vector quantities.
In physics, there are two types of quantities
Scalar quantityVector quantityScalar quantities are quantities that have magnitude but no direction. Examples of such quantities include speed, pressure, etc
Vector quantities are quantities that have both magnitude and direction. Examples of such quantities include velocity, acceleration etc.
Vector quantities are represented by an arrow over the position of the object to denote its direction.

what is the effective nuclear charge for a 2nd row electron in sulfur?
Sulfur valence electrons have an effective nuclear charge of +6.
What are effective nuclear charge?Effective nuclear charge is defined as the true positive nuclear charge that an electron in a multi-electron atom experiences. Electrons and protons are the two elements that cause the effective nuclear charge to rise. Zeff = Z - S is the actual nuclear charge.
A sulfur second row electron's effective nuclear charge is 14. Since sulfur contains 16 protons, or 16 atomic numbers, we know that there are 2 electrons in its first shell or orbit, which due to its rapid speed creates a shielding effect.
Thus, sulfur valence electrons have an effective nuclear charge of +6.

Explanation:
very far from earth (at r=[infinity]), a spacecraft has run out of fuel and its kinetic energy is zero. if only the gravitational force of the earth were to act on it (i.e., neglect the forces from the sun and other solar system objects), the spacecraft would eventually crash into the earth. the mass of the earth is me and its radius is re. neglect air resistance throughout this problem, since the spacecraft is primarily moving through the near vacuum of space.
By considering the conservation of energy, the speed V of the spacecraft when it eventually crash into the earth and its distance from the center of the earth is r are 11172.6 m/s and 3294.6 m/s respectively.
Given that, r is at infinity when a spacecraft has run out of fuel and its kinetic energy is zero. if only the gravitational force of the earth were to act on the spacecraft would eventually crash into the earth.
Where
Mass of the earth [tex]m_{e}[/tex] = 5.97 × [tex]10^{24}[/tex] kg
Radius of the earth [tex]R_{e}[/tex] = 6.38 × [tex]10^{6}[/tex] m
G = 6.67 x [tex]10^{-11}[/tex]N[tex]m^{2}kg^{-2}[/tex]
a.) Since the spacecraft is primarily moving through the near vacuum of space, the speed V of the spacecraft when it eventually crash into the earth can be calculated by considering the conservation of energy.
The total initial energy = total final energy.
[tex]E_{i} = E_{f}[/tex]
[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]
where [tex]K.E_{i}[/tex] = 0
-G[tex]m_{e}[/tex]m/(r + [tex]R_{e}[/tex]) = 1/2m[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex]m)/[tex]R_{e}[/tex]
mass of the spacecraft will cancel out
G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]
G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 0 since r is at infinity.
0 = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]
Substitute all the parameters into the equation above.
0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/6.38 x [tex]10^{6}[/tex]
0.5[tex]V^{2}[/tex] = 62,413,636.36
[tex]V^{2}[/tex] = 62,413,636.36 / 0.5
[tex]V^{2}[/tex] = 124,827,272.7
V = [tex]\sqrt{124,827,272.7}[/tex]
V = 11172.6 m/s
b.) Given that the distance from the earth r = x([tex]R_{e}[/tex])
That is,
r = 11.5 x 6.38 x [tex]10^{6}[/tex]
r = 73,370,000 m
To find the spacecraft's speed when its distance from the center of the earth is r, we will use the same formula. That is,
[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]
0 = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/r
Substitute all the parameters into the formula
0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/ 73,370,000
0.5[tex]V^{2}[/tex] = 5427272.727
[tex]V^{2}[/tex] = 10854545.45
V = [tex]\sqrt{10854545.45}[/tex]
V = 3294.6 m/s
Therefore, the speed V of the spacecraft when it eventually crash into the earth and its distance from the center of the earth is r are 11172.6 m/s and
3294.6 m/s respectively.

What must a scientist do in order to develop a testable hypothesis brainly.
Answer: The correct answer is D. Ask a question that can be answered by making observations.
Explanation:
Basically, in order to develop a testable hypothesis, scientists must adhere to the guidelines of the scientific method.
The scientific method is usually understood to be a so-called hypothetical-deductive method, the core of which is to make hypotheses based on observations or measurements, to make predictions based on them and to check the validity of predictions by repeated experiments. More generally, the scientific method is a general way of obtaining solid knowledge, using many means of proof, both empirical and theoretical, to achieve certainty. The scientific method is a widely recognized tool in the scientific community for seeking objectivity, reliability and transparency in research.
