A car battery has a rating of 250 ampere-hours. This rating is one indication of the total charge that the battery can provide t

Serga [27]

Answer:

Total charge provided by the battery could be 900000 C.

Maximum current provided by the battery for 37 minutes could be 405.405 A

Explanation:

Rating= 250 A-h

a. Total charge:

$Rating=Q/t\\Q=Rating.t\\$

Suppose t=1h

$Q=250 A(1h)\\Q=250 A(3600 sec)\\Q= 900000 A.sec$

We konw that $Ampere=\frac{Coulomb}{sec}$ , replacing:

$Q=900000(\frac{Coulomb}{sec})(sec)\\Q=900000 Coulomb$

Total charge provided by the battery could be 900000 C.

b. Maximum current for 37 minutes

$I=\frac{Q}{t} \\I=\frac{900000 C}{37*60 sec}\\I=405.405 A$

Maximum current provided by the battery for 37 minutes could be 405.405 A

Grace [21]

Answer:

Only the 4 th statement is true that is bed 1 and 3 are older than 4.

Explanation:

The 5 beds are numbered from 1 to 5 , 1 being the lowest and 5 being the topmost bed.

We are given 4 statements and we have to find out which all are true.

(a)Bed 4 is older than bed 2

This is wrong because the lower beds are older than beds that are higher.

(b)Bed 3 is older than beds 2 and 4

This is also wrong because the 2 is older than 3

(c)Bed 5 is the oldest

This is wrong because bed 1 is the oldest

(d)Beds 1 and 3 are older than 4

This is true as lower beds are older

Calculate the wavelength of an electron mass 9.1*10^-31kg moving with a velocity of 2.0*10^6m/s (h=6.63*10^-34Js) (Hint: De Brog

Inga [223]

Answer:

Wavelength, $\lambda=3.64\times 10^{-10}\ m$

Explanation:

We have,

Velocity an electron is $2\times 10^6\ m/s$

Mass of an electron is $9.1\times 10^{-31}\ kg$

It is required to find the wavelength of electron. The De-Broglie wavelength of an electron is given by :

$\lambda=\dfrac{h}{mv}$

h is Planck's constant

$\lambda=\dfrac{6.63\times 10^{-34}}{9.1\times 10^{-31}\times 2\times 10^6}\\\\\lambda=3.64\times 10^{-10}\ m$

So, the wavelength of an electron is $3.64\times 10^{-10}\ m$ .
