A small spaceship whose mass is 1300 kg (including an astronaut) is drifting in outer space with negligible gravitational forces
Alexxandr [17]

Answer:

Explanation:

Relation between energy and momentum is as follows .

E = h c / λ

E / c = h / λ

h /λ = momentum of a photon

momentum of a photon  = E /c

= 11 x 10³ / 3 x 10⁸

= 3.67 x 10⁻⁵

In 4 days no of photon

= 4 x 24 x 60 x 60 = 345600 .

momentum of photon released

3.67 x 10⁻⁵  x 345600 .

= 12.68 kg m/s

This momentum will be imparted to spaceship .

12.68 = mv

12 .68 = 1300 x v

v = .00975 m /s

= 9.75 mm /s

A stunt cyclist rides on the interior of a cylinder 13 m in radius. The coefficient of static friction between the tires and the
ZanzabumX [31]

Answer:

v=13.1m/s

Explanation:

From the question we are told that:

Radius r=13

Coefficient of static friction \mu=0.67

Given the Centripetal concept

Generally the equation for Velocity v is mathematically given by

v=\sqrt{\frac{gr}{\mu}}

v=\sqrt{\frac{9.81*13}{0.67}}

v=13.1m/s

The value of the minimum speed (in m/s) for the cyclist to perform the stunt is Given as

v=13.1m/s
