The wavelength of the baseball is 1.32×10−34m 1.32 × 10 − 34 m .

Wavelength can be defined as the distance between two successive crests or throughs of a wave.

To calculate the equivalent of a baseball having Mars 155 g moving at =25.3 m/s. (So in this question we used the concept of the equivalent and how to  prevalent the  related with article mass and velocity). So π that is equal to H divided by M. V. Where π is the equivalent and M is the mass of particle V. Is the velocity and H is the plank's constant whose value =6.6 26 <10 arrays to power minus 34 kg meter square and the  second universe. And this Mv basically we can be  call it as particles momentum. This is the  particle's momentum because momentum that is this P is equal to M into so in the  march into willow stream that is known as it is  momentum. Let us see to the  data given in the question we are given masks by  of the  baseball 1 55 g and we know one kg that is =2000 g. So we have to convert this mask in terms of the kg. So which is equal to the  point of= 1 55 kg.

And so this kg  cancel out second universities also to the   So on solving this time we get =1.689 into =10 arrays to power -34 m. So  this is the equivalent of to the  baseball, So hence they equivalent of the baseball and this is =1.689 ×10, raised to power -34 m.

The surface area of the filament is  4.66*10⁻⁴ m².

P = e*σ*A*T⁴

where,

P = radiating energy at a rate

e=  emissivity

σ = Stefan's Constant (5.67 *10⁻8 W/m².K⁴)

A= Surface Area

T = Temperature of the glowing filament (absolute temperature °K)

P = 60 w.

T  = 1500°C+ 273°K

   =1773°K

e= 0.23.

substituting into the equation:

P = e*σ*A*T⁴

60 w = 0.23. * 5.67 *10⁻8 W/m².K⁴ * A * (1773°K)⁴

Making A subject of the formula we have:

A =                  60 w                          

      0.23. * 5.67 *10⁻8 W/m².K⁴ * (1773°K)⁴

The width (in mm) of the central maximum on a screen 1.4 m behind the slit =  0.014 mm.

Diffraction of light on a single slit will produce maximum interference from the slit if the path difference between the light coming is:

(2n+1) ½ λ

Maximum interference if the difference in the paths taken by light from adjacent slits is equal to an integer multiple times the wavelength or also an even number times the half wave.

To determine the width from the maximum center on the screen behind the slit. use the equation:

Ym = mλD/a

We have,

a = 190 λ

So,

Y₁ = (1)λ (1.4) / 190 λ

= 0.007 m

And, width of the central maximum can be determined as:

Wc = 2Y₁

= 2 (0.007)

= 0.014 mm

The total of all forces acting on an object is known as the net force. A mass can accelerate due to net force.

The total of all forces acting on an object is known as the net force. A mass can accelerate due to net force. Whether a body is at rest or in motion, it is subject to another force. When there are a lot of forces acting on a system, the term "net force" is used.

here r12 = 0.550m r23= = 0.550m Then the distance from the first charge to the third one will be:

r13 =r12+r23=0.550+0.550 = 1.1m

According to the Coulomb's law, the net force on particle q2 will be equal to the sum of the forces on particle q2 from the particle q1 and q3.

F3+=F13+F23=q1q2/r²13 + k q3q2/r²23

Where k = 9×[tex]10^{9}[/tex] N m²/C²

Substituting numerical values, obtain:

F3= 9×[tex]10^{9}[/tex](-66.3 × [tex]10^{-6}[/tex])(-43.2×9×[tex]10^{-6}[/tex])/1.45²+9 ×[tex]10^{9}[/tex] 108×[tex]10^{-6}[/tex](-43.2 ×[tex]10^{-6}[/tex])/0.550²

When then the ball is stopped by the hand due to reaction force by the hand which is equal in magnitude but is opposite in direction to the force applied by the ball.

According to Newton's third law of motion, the reaction would be equal and opposite to the person pushing on the ball, so the ball pushing on the person.

When a ball is thrown on the floor or a wall, it bounces back. The force exerted by the ball on the ground or wall is the action force. The force that the ground or wall exerts on the ball in response to the action force causes the ball to jump or bounce back.

Answer:-An echo is heard sooner on a hot day because the speed of sound in air increases with temperature. So the speed of sound in air is more on a hot day, and an echo is heard sooner.                                             The velocity of sound in a gas is directly proportional to the square root of its absolute temperature (v=MρRT ). Since, temperature of a hot day is more than cold winter day, therefore sound would travel faster on hot summer day than on a cold winter day.                                                                     A reduction in pulse-echo amplitude was observed at all temperatures in the range and was found to be proportional to temperature increase.             Sound wave speed is dependent on air temperature. Sound waves move faster in warmer temperatures and slower in colder temperatures. During the day, temperatures are warmest near the surface and cool off with height. This is known as a lapse rate.                                                                            Due to the high energy of atoms on a hot day, sound travels faster compared to a cold day, where atoms don't have much energy to vibrate freely. Therefore, an echo will return more quickly on a hot day than on a cold day.

Superior forward visibility compared to radial or V-type engines is a benefit of horizontally opposed engines. For a variety of reasons, including fewer cylinders for equivalent power and smooth operation, opposed engines have today supplanted all previous forms of piston engines.

The American F4U-4 Corsair carrier-based fighter-bomber, created and manufactured by Chance Vought, was the most effective fighter of World War II. More than 12,500 aircraft were produced between 1942 and 1953. The fighter had an extremely lethal arsenal and outstanding mobility.

The requirement to gear the power from the two opposing pistons together was the biggest disadvantage. Compared to traditional piston engines, these extra weight and complexity

An electric current only produced if there is a closed circuit because without a closed circuit, electrons cannot flow from one point to another. That is option A.

An electric current is defined as the flow of charged particles through an electrical conductive pathway or space.

There are two types of electric current such as direct current (DC) and alternating current (AC).

For a current to flow to a circuit the circuit must be closed through the switch. This is because a closed circuit ensures that the pathway is complete to prevent the loss of energy.
