Which type of bone is this covalent bondhydrogen bond ionic bond​

Physics
1 answer:
Fynjy0 [20]4 years ago
5 0

Answer:

Explanation:A covalent bond is formed when electrons are shared between non-metal atoms, and the positive nuclei are attracted towards the pair of negative bonded electrons. ... Hence, the hydrogen bond is weaker than ionic and covalent bonds. Example: Water molecules are held to each other by intermolecular forces of attraction.

A 4-kg block is sliding down a plane as pictured, with the plane forming a 3-4-5 right triangle. Initially, the block is not mov
Andru [333]

Answer:b

Explanation:

Given

mass of block m=4 kg

coefficient of static friction \mu =0.25

height of triangle is h=3 m

F_{net}=mg\sin \theta -\mu _kmg\cos \theta

a_{net}=g\sin \theta -\mu _kg\cos \theta

a_{net}=9.8\sin 37-0.25\times 9.8\times \cos 37

a_{net}=5.897-1.956=3.94 m/s^2

here s=5 m

v^2-u^2=2 a_{net}s

v=\sqrt{2\times 3.94\times 5}

v=6.27 m/s

time taken to reach bottom of plane

v=u+at

6.27=0+3.94\times t

t=1.59 s\approx 1.6 s
