A student submerges an irregularly object in a graduated cylinder half filled with water. The level of the water in the cylinder

rises from 17.8 ml to 49.7 ml. If the density of water is 0.9984 kg/liter, calculate the mass of the object in grams. The use of correct number of significant figures is required in answering all questions.

solution:

volume of cylinder = change in level of water

volume of cylineder=(49.7-17.8)mL

=31.9mL

=0.0319liter

Mass= density x volume

=09984 x 0.0319

=0.0318kg

=31.8gm

How does temperature affect Brownian motion
Elan Coil [88]

Answer:

Explanation:

Temperature is the measure of average kinetic energy or energy in motion in a molecules. Brownian motion measure kinetic energy or how energetic the motion is and it is proportional to temperature.

Therefore, an increase in Temperature will bring about increase in kinetic energy of brownian motion. It will speed it up.

How high would a projectile go if it was launched from ground level with an initial speed of 26 m/s at an angle of 30 degrees ab
tigry1 [53]

Answer:

Vy = 26 m/s sin 30 = 13 m/s      vertical speed

t = Vy / a = 13 m/s / 9.80 m/s^2 = 1.33 sec     time to reach Vy = 0

H = Vy t + 1/2 g t^2

H = 13 m/s * 1.33 sec - 1.33^2 * 9.8 / 2 m = 8.62 m

deff fn [24]

Explanation:

Kirchhoffs Voltage Rule, or KVL, explains that "the overall voltage throughout the circuit in any closed loop network is equal to the sum of all voltage decreases inside the same loop" which is equivalent to zero. In other words, the mathematical sum of all within the loop voltages must be equal to zero.
