How do you get: a = -ω^2*x from: a = -Aω^2*sen(ωt) ?

Firdavs [7]

Answer:

$x = Asin(\omega t)\\v = \frac{dx}{dt} = \omega Acos(\omega t)\\a = \frac{dv}{dt} = -\omega^2Asin(\omega t)= -\omega^2x$

A weight lifter lifts a 1.0 x 103 N weight 1.5 m in 2.0 s. The power is?

viktelen [127]

Answer:

750W

Explanation:

Given parameters:

Weight = 1 x 10³N = 1000N

Distance = 1.5m

Time = 2s

Unknown:

Power = ?

Solution:

Power is the rate at which work is done

Work is the force applied on a body to move it through a particular distance

Work = force x distance

Power = $\frac{work}{time}$

Now, work = 1000 x 1.5 = 1500J

So;

Power = $\frac{1500}{2}$ = 750W

A flat loop of wire consisting of a single turn of cross-sectional area 7.10 cm2 is perpendicular to a magnetic field that incre

Lina20 [59]

Answer:

The induced current is $I = 0.00066 \ A$

Explanation:

From the question we are told that

The area is $A = 7.10 \ cm^2 = 7.10 *10^{-4} \ m^2$

The initial magnetic field is $B_i = 0.500 \ T$

The magnetic field after t =1.07 s is $B_f = 2.10 \ T$

The resistance of the loop is $R = 1.60 \ \Omega$

Generally the electromagnetic field induced is mathematically represented as

$\epsilon = NA * \frac{B_f - B_i}{t}$

Where N is the number of turns which is 1 in the case of this question since there is only one loop

$\epsilon = 1 * 7.10*10^{-4}* \frac{2.10 - 0.500}{1.07 }$

=> $\epsilon = 0.00106 \ V$

Generally the value of the current is mathematically represented as

$I = \frac{\epsilon}{R}$

$I = \frac{0.00106}{1.60}$

$I = 0.00066 \ A$

If a moving body of mass 100g has kinetic energy 45 joules, what will be it's velocity?

Pavel [41]

Answer:

$\boxed{\pink{\sf Velocity \ of \ the \ body \ is \ 30m/s .}}$

Explanation:

Given that a body is moving which has a mass of 100g. And its Kinetic energy is 45 Joules . We need to find its velocity . So ,

$\boxed{\red{\bf Kinetic\: Energy =\dfrac{1}{2}mv^2 }}$

Now here mass is in grams. So converting it into SI units we have , 100/1000 kg = 0.1 kg

$\implies KE =\dfrac{1}{2}mv^2 \\\\\implies 45 J = \dfrac{1}{2}\times \dfrac{1}{10} kg \times v^2 \\\\\implies v^2 = 45 \times 20 \\\\\implies v^2 = 900 m^2/s^2 \\\\\implies v =\sqrt{900 m^2/s^2} \\\\\underline{\boxed{\blue{\tt \implies Velocity = 30m/s }}}$
