What is the smallest time interval in which a 5.7 T magnetic field can be turned on or off if the induced emf around the patient

VLD [36.1K]

The smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.

<h3>Emf induced in the coil</h3>

The emf induced in the coil is calculated as follows;

emf = dФ/dt

where;

dФ is change in flux
dt is change in time

0.12 = 5.7/dt

dt = 5.7/0.12

dt = 47.5 s

Thus, the smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.

A 200g of iron at 120 degrees and a 150 g piece of copper at -50 degrees are dropped into an insulated beaker containing 300 g o

kodGreya [7K]

Answer:

T = 15.03°C

Explanation:

given data:

copper specific heat = Sc = 0.385 J/g °C

iron specific iron = Si = 0.450 J/g °C

specific heat of ethanol = Se = 2.46 J/g °C

net heat loss is equal to zero

$(m*S*\Delta T)_{copper} +(m*S*\Delta T)_ {iron} +(m*S*\Delta T)_ {ethanol} = 0$

$150*0.385 *( T - (-50)) + 200*0.450*(T - 120) + 300*2.46 * (T -20) = 0$

$57.75( T - (-50)) + 0.90(T - 120) +738(T -20) = 0$

$57.75T + 2887.5 + 0.90T - 108 + 738T - 14760 = 0$

$57.75T + 0.90T+738T = - 2887.5 + 108+14760$

$796.65T= 11980.5$

T = 15.03°C

Astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. The Body Mas

anzhelika [568]

Answer:

55 kg

Explanation:

spring constant (k) = 600 N/m

mass of chair (Mc) = 12 kg

period of oscillation of chair and man (T) = 2.1 s

what is the mass of the astronaut (Ma) ?

mass of the astronaut (Ma) = total mass (Mt) - mass of chair (Mc)

where

total mass (Mt) = $\frac{T^{2}}{4π^{2}}k$

taking π as 3.142

total mass (Mt) = $\frac{2.1^{2}}{4 x 3.142^{2}}600$

total mass (Mt) = 67 kg

therefore

mass of astronaut = 67 - 12 = 55 kg

Please help.

Alex787 [66]

Explanation:

mathematically,

$kinetic \: energy \: = \frac{1}{2} m {v}^{2}$

where m= mass

and v=velocity

given that,

kinetic energy=493900J

mass =5040kg

making velocity the subject

$v = \sqrt{ \frac{2 \times kinetic \: energy}{mass} }$

substitute their values in the formula

$v = \sqrt{ \frac{2 \times 493900}{5040} }$

$v = \sqrt{ \frac{987800}{5040} }$

$v = \sqrt{196}$

$v = 14m {s}^{ - 1}$

Thus the velocity is 14meters per second
