Answer:

a) Team A will win.

b) The losing team will accelerate towards the middle line with 0.01 m/ $s^{2}$

Explanation:

Given that Team-A pulls with a force , $F_{1} = 50N$

and Team-B pulls with a force , $F_{1} = 45N$

∵ $F_{1} > F_{2}$

The rope will move in the direction of force $F_{1}$ .

∴ Team-A will win.

b) Considering both the teams as one system of total mass , $m = 246+253 = 499 kg$

Net force on the system , $F = F_{1} - F_{2}$ = 50-45 = 5N

Applying Newtons first law to the system ,

F = ma , where 'a' is the acceleration of the system.

Since , both the teams are connected by the same rope , their acceleration would be the same.

∴ 5 = 499×a

∴ a = 0.01 m/ $s^{2}$

When energy is added to a fl uid, the temperature of the fl uid increases. an equation describing this phenomenon is:_________

Ksju [112]

The temperature of a fluid rises when energy is given to it. This phenomenon can be described by the equation:

Q = MCp ΔT

where,

Q is the quantity of added energy.

M is the fluid's mass.

The fluid's heat capacity is denoted by Cp.

T stands for temperature change.

<h3>What happens to a fluid's kinetic energy as the temperature rises?</h3>

The mean kinetic energy of the particles in a liquid rises with temperature. The molecules' higher average kinetic energies allow them to more easily overcome the attraction forces that keep them bound together.

<h3>Which temperature rise makes liquids more fluid?</h3>

The most significant determining factor for fluidity is pouring temperature. Therefore, the fluidity increases as the pouring temperature increases.

<h3>How does a liquid react when the temperature rises?</h3>

Particles in a solid, liquid, or gas move more quickly as its temperature rises. The particles slow down as the temperature drops. When a liquid is sufficiently cooled, it turns into a solid.

The output voltage of a power supply is V = Vo Sin (120t). At t = 0.01 s, the output voltage is 4.2 V. What is the rms voltage o

dexar [7]

Answer:

3.18 V

Explanation:

RMS voltage of a generator is given by:

$V_{rms}=\frac{1}{\sqrt 2}V_o$

Given:

Output voltage at t =0.01 s is 4.2 V

$V = V_o sin (120t)\\ 4.2 = V_o sin (120 \times 0.01) \\ V_o = 4.5 V$

$V_{rms}=\frac{1}{\sqrt 2}4.5 V = 3.18 V$

How did the study of the atom contribute to our understanding of the periodic table of the elements? (1 point) Atoms are represe

Dvinal [7]

The study of the atom contribute d to our understanding of the periodic table of the elements by virtue of the following;

Elements are made of atoms, so understanding atoms provided information about elements, which led to the organization of the periodic table

Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.

As we know; the periodic table is an array of elements in order of their atomic number.

In which case, the periodic table is made up of 7 rows otherwise called Periods and 8 columns otherwise called Groups.
