Answer:

Newtons first law states that:

If a body is in rest or motion in a straight line, it remains at rest or at motion in a straight line with constant speed until and unless and external unbalanced force acts on it.

'This law is also known as the law of Inertia.'

Answer:

W=0.217kJ

Explanation:

#Boundary Work is energy expended when a force acts through a displacement

The boundary of work can be calculated as the area under the P-V curve for all the 4 stages measured:

$W= \sum_{n=1}^{5} \frac{P_{n+1}+P_{n+2}+P_{n+3}+P_{n+4}+P_{n+5}}{2}\\\\=0.5((290+300)(1.1-1)+(270+290)(1.2-1.1)+(250+270)(1.4-1.3)+(220+250)(1.7-1.4)+(200+220)(2-1.7))\times 10^-^3kJ\\\\=0.217kJ$

Hence the boundary of work done by a gas during this 4-stage process is 0.217kJ

blondinia [14]

Answer:

In an electromagnetic wave in free space, the ratio of the magnitudes of electric and magnetic field vectors E and B is equal: speed of light(c)

Explanation:

Generally the ratio of the E(electric field ) and the B(magnetic field ) is equal to the speed of the electromagnetic wave i.e the speed of light (c) the value is

$c = 3.0 *10^{8} \ m/s$

Answer:

$v=87.46m/s$

Explanation:

Objects moving in circular path would be have either centripetal or centrifugal force.The force is either to center or away from center. When the object is moving along the circular path the centripetal force is

$F=\frac{mv^{2}}{r}$

Here m is mass, v is velocity and r is radius of circular path

The acceleration is given by:

$a_{r}=\frac{v^{2}}{r}$

The point of interest is lowest point on circle.The acceleration of plane at this position point up.The speed of plane from radial acceleration equation is:

$v=\sqrt{a.r}\\$

Substitute 17 m/s² for a and 450m for r

$v=\sqrt{17m/s^{2}*450m }\\ v=87.46m/s$
