Explanation:

you have to MEASURE the velocity of both then divide.remember when DIVIDING the number GETS LOWER not higher.

Answer:

The GENERAL formula for this PROBLEM is:

%left = (1/2)^(TIME PAST / half-life)

In this case, %left = (1/2)^(20/5) = 0.5^4 = 0.0625 = 1/16

Consider 18 minutes:

%left = (1/2)^(18/5) = 0.5^3.6 = 0.0825

Explanation:

When an IDEAL capacitor is charged by dc BATTERY, charge flows momentarily till the capacitor gets fully charged .Ideal capacitor means infinte resistance for dc.

When an ac source is connected to the capacitor, conduction current, ic=dtdq continuously flows in the connecting wire. DUE to changing current, charge deposited on the plates of the capacitor changes with time.This causes change in electric field between the plates of the capacitor which cause the electric flux to change and gives rise to the displacement current in the region between the plates of the capacitor.

Displacement current is GIVEN by,

id=ϵodtdϕE and id=ic at all instant.

Explanation:

In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will PROPAGATE randomly at the Fermi velocity, resulting in an average velocity of zero. Applying an electric field adds to this random MOTION a small net flow in one direction; this is the drift.

Drift velocity is proportional to current. In a resistive material it is also proportional to the magnitude of an EXTERNAL electric field. Thus Ohm's law can be explained in terms of drift velocity. The law's most elementary expression is:

{\displaystyle u=\mu E,}u=\mu E,

where u is drift velocity, μ is the material's electron mobility, and E is the electric field. In the MKS system these quantities' units are m/s, m2/(V·s), and V/m, respectively.

When a potential difference is applied across a conductor, FREE electrons gain velocity in the direction opposite to the electric field between successive collisions (and lose velocity when traveling in the direction of the field), thus acquiring a velocity component in that direction in addition to its random THERMAL velocity. As a result, there is a definite small drift velocity of electrons, which is superimposed on the random motion of free electrons. Due to this drift velocity, there is a net flow of electrons opposite to the direction of the field.

Answer:

Propaganda films were made to create hatred for Jews. The most infamous film was The Eternal Jew. Orthodox Jews were stereotyped and marked. They were shown with flowing BEARDS WEARING kaftans. They were referred to as VERMIN, rats, and PESTS. Their movements were compared to those of rodents. Orthodox Jews were stereotyped as killers of Christ and moneylenders. Stereotypes about Jews were popularised EVEN through Maths classes. Children were taught to hate the Jews. The Nazi propaganda against the Jews was so effective that people felt anger and hatred surge inside them when they saw someone who looked like a Jew.

Answer:

The nucleoid (meaning NUCLEUS-like) is an irregularly shaped region within the prokaryotic CELL that contains all or most of the genetic material.[1][2][3] The chromosome of a prokaryote is circular, and its length is very large compared to the cell dimensions needing it to be compacted in order to fit. In contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane. Instead, the nucleoid forms by condensation and functional arrangement with the help of CHROMOSOMAL architectural proteins and RNA molecules as well as DNA supercoiling. The length of a genome widely VARIES (generally at least a few million base pairs) and a cell may contain multiple copies of it.

न्यूटन के गति नियम तीन भौतिक नियम हैं जो चिरसम्मत यांत्रिकी के आधार हैं। ये नियम किसी वस्तु पर लगने वाले बल और उससे उत्पन्न उस वस्तु की गति के बीच सम्बन्ध बताते हैं। इन्हें तीन सदियों में अनेक प्रकार से व्यक्त किया गया है।[1] न्यूटन के गति के तीनों नियम, पारम्परिक रूप से, संक्षेप में निम्नलिखित हैं-

प्रथम नियम: प्रत्येक पिण्ड तब तक अपनी विरामावस्था में अथवा सरल रेखा में एकसमान गति की अवस्था में रहता है जब तक कोई बाह्य बल उसे अन्यथा व्यवहार करने के लिए विवश नहीं करता। इसे जड़त्व. का नियम भी कहा जाता है.

द्वितीय नियम: किसी भी पिंड की संवेग परिवर्तन की दर लगाये गये बल के समानुपाती होती है और उसकी (संवेग परिवर्तन की) दिशा वही होती है जो बल की है।

HOPE it'll HELP you .

Answer:

Time taken to travel FIRST HALF distance = 100/ 50 = 2 hrs

Time is taken to travel SECOND half distance = 100/v

Average speed = 200/ (2 + 100/v)

70 = 200/ (2 + 100/v)

2 + 100/v = 20/7

100/v = 20/7 – 2 = 6/7

v = 100 * 7/6 Km/h

v = 700/6 km/h

Explanation:

Dimensional ANALYSIS can't derive relation or formula if a physical quantity depends UPON more than three FACTORS having dimensions. It can't derive a formula containing TRIGONOMETRIC function, exponential function, and logarithmic function and it can't derive a relation having more than one part in an equation.

Explanation:

Given:-

• Mass of BALL ,m = 42g

• Initial velocity ,u = 15.6m/s

• Final velocity ,V = 0m/s

• Acceleration due to gravity ,g = 9.8m/s

To Find:-

• Height ,h

Solution:-

We have to calculate the height ATTAINED by the ball after bounce. Using 3rd Equation of Motion

• v² = u² +2gh

v is the final velocity

g is the acceleration

u is the initial velocity

h is the height attained

Substitute the value we get

→ 0² = 15.6² + 2×(-9.8) × h

→ 0 = 243.36 + (-19.6) ×h

→ -243.36 = -19.6×h

→ h = -243.36/-19.6

→ h = 243.36/19.6

→ h = 12. 41 m

Therefore, the height attained by the ball is 12.41 Metres.

Explanation:

Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. Time travel is a widely recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. WELLS's 1895 novel The Time Machine.[1]

It is uncertain if time travel to the past is physically possible. Forward time travel, outside the usual sense of the perception of time, is an extensively observed phenomenon and well-understood within the framework of special relativity and general relativity. HOWEVER, making one body advance or delay more than a few milliseconds compared to another body is not FEASIBLE with current technology. As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating BLACK hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually CONNECTED only with quantum mechanics or wormholes.

Given:-

• Velocity ,V = 2.54 m/s²

• KINETIC ENERGY ,KE = 193 J

To Find:-

• Combined mass of girl and bike ,m

Solution:-

As we KNOW that the energy posses by body due to its motion is called Kinetic Energy.

• KE = 1/2mv²

Where,

KE is the Kinetic Energy

m is the mass

v is the velocity

Substitute the value we get

→ 193 = 1/2×m × 2.54²

→ 193 = 1/2×m × 6.45

→ 193×2 = m×6.45

→ 386 = m × 6.45

→ m = 386/6.45

→ m = 59.83 ≈ 60 kg

Therefore, the combined mass of the girl and her bike is 60 Kg.
