Derived from the Hebrew יִצְחָק (Yitzhak), the name Isaac means “one who laughs” or “one who rejoices.” In the Old Testament of the Bible, Isaac is the firstborn son of Abraham. He is one of the three biblical patriarchs revered by Jews, Christians, and Muslims. ... Gender: Isaac is traditionally a masculine name.

A block with mass M = 7.50 kg is initially moving up the incline with speed v 0 and is increasing speed with acceleration a = 3

valina [46]

Answer:

F = 96.11 N

friction force =33.48 N

Explanation:

given,

mass of block M = 7.50 kg

acceleration = 3 m/s²

µ s = 0.443 and µ k = 0.312

angle with the horizontal = 25°

the component of force along the incline is F cos theta

normal reaction ,

$N = mg cos \theta + F sin \theta$

$N = 7.5\times 9.81\times cos25^0 + F sin 25^0$

N = 66.68+ .423 F

for the mass

$F cos \theta - mg sin \theta - \mu_k\ N = ma$

$F cos 25^0 - 7.5\times 9.81\times sin 25^0 - 0.312\times ( 66.68+ .423 F) = 7.5\times 3$

0.906 F - 0.132 F - 31.09 - 20.8 = 22.5

0.774F = 74.39

F = 96.11 N

normal force ,

N = 66.68 + .423×96.11

=107.33 N

friction force = .312 × N

= 0.312× 107.33

friction force =33.48 N

The luminous flux of a torch of intensity 50 cd is?

RSB [31]

Answer:

i dont know i am right but here Luminous intensity is defined as dI=dΨλ / dΩ, where dΨλ is the luminous flux (light energy flux in watts per m2) emitted within a solid angle dΩ. The light energy flux may be expressed in terms of the incident x-ray energy flux and the x-ray absorption and conversion properties of the scintillator(7,8,9).
