Answer: Option (B) is the correct answer.

Explanation:

A solid which is not soluble and has formed from the liquid solution is known as a precipitate.

For example, when lemon juice is added to milk then it results in the formation of paneer (cheese) that is insoluble.

Hence, we can conclude that during the addition of lemon juice into milk will bring a chemical change by forming a precipitate.

A stream of water strikes a stationary turbine blade horizontally, as the drawing illustrates. The incident water stream has a v

bulgar [2K]

Answer:

F = 1908 N

Explanation:

GIVEN,

Incident water stream has a velocity = U = +18.0 m/s,

Exiting water stream has a velocity = V = -18.0 m/s.

Mass of water per sec : M / t = 53 kg /s

Change in velocity d v =18 m / s – ( -18 m / s)

= 36 m / s

Magnitude of the average force exerted on the water by the blade

F = ( M / t ) x dv

=( 53 kg /s ) x ( 36 m/s )

F = 1908 N

suppose the spring in the sample problem is replaced with a spring that stretches 36 cm from its equilibrium position

amm1812

The gravitational force is acting downward as the spring is held vertically. Therefore, spring is stretched downward and the force is directly proportional to the stretched distance. The product of the mass and the gravitational acceleration gives gravitational force.

A 0.0208 m diameter coin rolls up a 18.0◦ inclined plane. The coin starts with an initial angular speed of 56.0 rad/s and rolls

anastassius [24]

Answer:

h = 0.0259 m

Explanation:

given,

diameter of the cone = 0.0208 m

radius,r = 0.0104 m

angle of inclination,θ = 18°

initial angular velocity, ω_i = 56 rad/s
