7. Convert 746 days to centuries.

timofeeve [1]

Answer: 0.0208 Centuries

Explanation:

There is 2.739*10^-5 centuries per 1 day.

We can take 746 days and multiply it by that 2.7 number to get how many centuries are in 746 days.

$746 *(2.793*10^{-5})$ = 0.0208 centuries

An electron of mass 9.11×10−31 kg leaves one end of a TV picture tube with zero initial speed and travels in a straight line to

dedylja [7]

Answer:

$F=1.509\times 10^{-16}N$

Explanation:

We have given that mass of electron $m=9.11\times 10^{-31}kg$

It is given that initial velocity u=0 m/sec

Final velocity v = $2.7\times 10^6m/sec$

Distance S = 2.2 cm = 0.022 m

According to third law of motion $v^2=u^2+2as$

$(2.7\times 10^6)^2=0^2+2\times a\times 0.022$

$a=165.68\times 10^{12}m/sec^2$

Accelerating force F is given by F = ma

So accelerating force $F=9.11\times 10^{-31}\times 165.68\times 10^{12}=1.509\times 10^{-16}N$

Calculate change in height of a 2kg ball moving a speed of 10m/s up a frictionless ramp until it stops

Nataliya [291]

The change in the height of the object is 5.1 m.

<h3>Conservation of mechanical energy</h3>

The principle of conservation of mechanical energy states that the total energy of an isolated system is always conserved.

The change in the height of the object is calculated by applying the principle of conservation of mechanical energy as follows;

P.E = K.E

$mg \Delta h = \frac{1}{2} mv^2\\\\g \Delta h = \frac{1}{2}v^2\\\\\Delta h = \frac{v^2}{2g} \\\\\Delta h = \frac{(10)^2}{2(9.8)} \\\\\Delta h = 5.1 \ m$

Thus, the change in the height of the object is 5.1 m.
