Answer: D <u>(chemical</u> -> <u>heat</u> -> <u>mechanical</u>)
In automobile engines the petrol/diesel fuel enter in to the engine cylinder, due to spark at the end of the compression, fuel burnt increase the temperature and pressure, develops heat <em>(chemical energy -> heat energy). </em><em>This heat energy acts on a piston develops the work on the crankshaft </em><em>( Heat energy -> Mechanical energy)</em><em>. </em>
Answer:
A: 3 Mg, 2 P, 14 O, 12 H
Explanation:
I took the test on Edgenuity
Answer:
10989.55932 rad/s
Explanation:
m = Mass of object
M = Mass of neutron star = 
R = Radius of neutron star = 13000 m
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Angular speed
Here, the gravitational force will balance the centripetal force
The greatest possible angular speed an object can have is 10989.55932 rad/s
Answer:
There is a decrease in modulus of elasticity
Explanation:
Young's Modulus of elasticity also known as elastic modulus is the deformation of a body along a particular axis under the action of opposing forces along that axis. at atomic levels, it depends on bond energy or strength.
In cold working processes, plastic deformation a metal occurs below its re-crystallization temperature due to which crystal structure of metal gets distorted and as a result of dislocations fractures also occur resulting in hardening of metal but bonds at atomic levels defining elasticity are temporarily affected.
Thus an increase in cold working results in a decrease in modulus of elasticity.
