Answer:

2.5×10-²⁷ J

Explanation:

KE=1/2MV²

$m = 10 {}^{ - 27} kg$

$v = 18 \times (5 \div 18) = 5 \frac{m}{s {}^{} }$

Answer» Answer: The observations made by Rutherford LED him to conclude that: 1)A major fraction of the α-particles bombarded towards the gold sheet PASSED through it without any deflection, and HENCE most of the space in an atom is empty. 2)Some of the α-particles were deflected by the gold sheet by very small angles, and hence the positive charge in an atom is not UNIFORMLY distributed. The positive charge in an atom is concentrated in a very small volume. 3)Very few of the α-particles were deflected back, that is only a few α-particles had nearly 180o angle of deflection. So the volume occupied by the positively charged particles in an atom is very small as compared to the total volume of an atom.

Answer» Given : Initial velocity of the car = 39 km/hr final velocity of the car = 75km/hr Time taken = 10 sec To find : The acceleration of the car Solution : FIRSTLY we have to convert km/hr to m/s we KNOW that, » 1km/hr = 5/18km/hr » 39km/hr = 39 × 5/18 = 10.8 m/s » 75km/hr = 75 × 5/18 = 20.8 m/s Accerlation is the rate of CHANGE of velocity. It is a vector quantity having both MAGNITUDE as well as direction. SI unit of acceleration is metre per second square. As we are provided with initial velocity, final velocity and time we can use first equation of kinematics that is, v = u + at v denotes final velocity u denotes initial velocity a denotes acceleration t denotes time taken by substituting all the given values in the formula, ➝ v = u + at ➝ 20.8 = 10.8 + a(10) ➝ 20.8 - 10.8 = 10a ➝ a = 10/10 ➝ a = 1m/s² Thus, the acceleration of the car is 1m/s². $\:$

A car increases its speed from 39 km/hr to 75 km/hr in 10 seconds. Its acceleration is a) 3 m/s2 b) 0.8 m/s 2 c) 1 m/s2 d) 8 m/s2

Answer»

Given :

Initial velocity of the car = 39 km/hr

final velocity of the car = 75km/hr

Time taken = 10 sec

To find :

The acceleration of the car

Solution :

FIRSTLY we have to convert km/hr to m/s

we KNOW that,

» 1km/hr = 5/18km/hr

» 39km/hr = 39 × 5/18 = 10.8 m/s

» 75km/hr = 75 × 5/18 = 20.8 m/s

Accerlation is the rate of CHANGE of velocity.

It is a vector quantity having both MAGNITUDE as well as direction.
SI unit of acceleration is metre per second square.

As we are provided with initial velocity, final velocity and time we can use first equation of kinematics that is,

v = u + at

v denotes final velocity
u denotes initial velocity
a denotes acceleration
t denotes time taken

by substituting all the given values in the formula,

➝ v = u + at

➝ 20.8 = 10.8 + a(10)

➝ 20.8 - 10.8 = 10a

➝ a = 10/10

➝ a = 1m/s²

Thus, the acceleration of the car is 1m/s².

Answer» $\huge\small\fbox\colorbox{neon}{Hello User}$ The MEAN VALUE or average value of AC over a complete cycle is zero. So we do not consider the average value of AC over one cycle. We, THEREFORE, take the average value of AC over a half cycle only I.e. from t=0 to t= 2 T The average value of AC over a half cycle is that value of steady current that would SEND same amount of charge in same INTERVAL of time that would be sent by the DC in the same time. To calculate the mean value of ac, Let us consider an Ac given by The small amount of charge sent by an ac in small time dt is The total charge carried by ac in half cycle is obtained by integrating equation ii from t=0tot= 2 T If Im be the average ac then charge carried by it in half cycle is Now, we get Similarly, the average value of ac over the negative half cycle (t= 2 T tot=T) is Therefore the average ac over a complete cycle is zero.
