Answer:

E =  7.99 *10^{-13} J

Explanation:

the given reaction is

_1 H^1 + _1 H^2 = _2 He^3

we know that energy is given asE = \Delta mc^2E = (m_1 H^1 + m_1 H^2  - _2 He^3)c^2

where

m_1 H^1 is mass of proton = 1.672622 *10^{-27}

m_1 H^2 is mass of deuterium = 3.344494 *10^{-27}

m_2 H^3 is mass of He = 5.008234 *10^{-27}

E = [1.672622 *10^{-27} + 3.344494 *10^{-27} - 5.008234 *10^{-27} ] *(3*10^8)^2

E =  7.99 *10^{-13} J

Suppose the first coil of wire illustrated in the simulation is wound around the iron core 7 times. Suppose the second coil is w
SVETLANKA909090 [29]

Answer:

Emf induced in the coli will be equal to 26 volt

Explanation:

We have given number of turns N = 13

It is given that magnetic flux changes from 2.1 Weber to 2.7 Weber in 0.3 sec

Change in flux d\Phi =2.7-2.1=0.6Weber

Change in time dt = 0.3 sec

We have to find the induced emf

Induced emf is equal to e=N\frac{d\Phi }{dt}=13\times \frac{0.6}{0.3}=26volt

So emf induced in the coil will be equal to 6 volt

Estimate (a) the maximum, and (b) the minimum thermal conductivity values (in W/m-K) for a cermet that contains 83 vol% carbide
velikii [3]

Answer:

  k_max = 31.82 w/mk

  k_min  = 17.70 w/mk

Explanation:

a) the maximum thermal conductivity is given as

k_{max} = k_m*v_m + k_p*v_p

where k_m is thermal conductvitiy of metal

k_p is thermal conductvitiy of carbide

v_m = proportion of metal in the cement = 0.17

v_p = proportion of carbide in the cement = 0.83

            = 66*0.17 + 28*0.83

           k_max = 31.82 w/mk

b) the minimum thermal conductivity is given as

k_{min} = \frac{k_{carbide}* k_{metal}}{k_{metal} v_{carbide} +k_{metal} v_{carbide}}

          = \frac{28+66}{28*0.17 +66*0.83}

       k_min  = 17.70 w/mk

A river flows due south with a speed of 5.00 m/s. A man steers a motorboat across the river; his velocity relative to the water
Hunter-Best [27]

Answer:

6.4 m/s

Explanation:

From the question, we are given that

Speed of the river, v(r) = 5 m/s

velocity relative to the water, v(w) = 4 m/s

Width of the river, d = 780 m

The magnitude of his velocity relative to the earth is v(m)

v(m) can be gotten by using the relation

[v(m)]² = [v(w)]² + [v(r)]²

[v(m)]² = 4² + 5²

[v(m)]² = 16 + 25

[v(m)]² = 41

v(m) = √41

v(m) = 6.4 m/s

thus, the magnitude of the velocity relative to earth is 6.4 m/s
