Spitting cobras can defend themselves by squeezing muscles around their venom glands to squirt venom at an attacker. suppose a spitting cobra rears up to a height of 0.400 m above the ground and launches venom at 3.70 m/s, directed 57.0° above the horizon. neglecting air resistance, find the horizontal distance (in m) traveled by the venom before it hits the ground.

the correct choice is a .

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
