Mrs. Fatima has a a small sports car that she uses to drop her kids off from school that has a mass of 5000 kg. Mr. Zaid drives

a truck with a mass of 4200 kg. If the two vehicles are travelling down the road, side by side, at a speed of 75 km/hr, which one will have the most momentum? Explain *

\textbf{Use equation of momentum}

p=mv

\text{momentum\ =\ mass x velocity}

\textbf{Substitute in the values}

5000 \times 75 = 375,000 \text{\ kg\ km/hr}

4200 \times 75 = 315,000 \text{\ kg\ km/hr}

\textbf{The\ small\ sports\ car\ will\ have\ the\ most\ momentum.}

How do you graph motion in physics? How do you graph motion in physics? I've seen problems state that an object is in free fall
Dahasolnce [82]

This is Kinematics and the equations in your book.

A speed time graph would plot the speed of something against the teime it was at a speed.

If it were changing it speed constantly, that would be a straight line if acclerating. Total distrance would be the area under the graph.

A 2.0 kg mass weighs 10 Newtons on planet X. what is the acceleration due to gravity on planet X? Show the work.
KengaRu [80]

Answer: The gravitational acceleration on planet X is 5 N/kg

On Earth (with the gravitational accelartion g_E) the mass of 2kg will correspond to

F_E = m\cdot g_E = 2.0 \mbox{kg}\cdot 9.8 \frac{N}{kg} = 19.6 N

On planet X we are told the same measure is only 10N. Since there is a proportional relationship between g and F, we can calculate g_X:

\frac{F_E}{g_E}=\frac{F_X}{g_X} \implies\\g_x = \frac{g_E\cdot F_X}{F_E}=\frac{9.8 N/kg \cdot 10 N }{19.6N}=5 \frac{N}{kg}

What is entropy and how is it related to string theory?
balu736 [363]

Answer:

Explanation:

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. String theory also requires six or seven extra dimensions of space, and it contains ways of relating large extra dimensions to small ones. In statistical mechanics, entropy is an extensive property of a thermodynamic system. It quantifies the number Ω of microscopic configurations that are consistent with the macroscopic quantities that characterize the system theyre related  It later developed into superstring theory, which posits a connection called supersymmetry between bosons and the class of particles called fermions. Five consistent versions of superstring theory were developed before it was conjectured in the mid-1990s that they were all different limiting cases of a single theory in 11 dimensions known as M-theory. In late 1997, theorists discovered an important relationship called the AdS/CFT correspondence, which relates string theory to another type of physical theory called a quantum field theory.
