I believe the answer is H for when you bounce it, it has stress when it hits the floor and then goes up giving it kinetic
Vx = 2*cos30 = 1.73m's
Other words:
D = Vo*t = 1.4 * 21 = 31.5m. @ 30 Deg.
Dy = 31.5*sin30 = 15.75 m.
Answer:
Maximum velocity will be 17.651 m /sec
Explanation:
We have given a rope breaks when tension reaches 205 N
Mass m = 0.477 kg
Radius of the circle r = 0.725 m
Tension in the rope is given by
v = 17.651 m /sec
Answer: 0.24g/ml
Explanation:
Given that:
Volume of water displaced = 23.5 ml
Mass of cork = 5.7 g
Density of the cork = ?
Recall that density is obtained by dividing the mass of a substance by the volume of water displaced.
i.e Density = Mass/volume
Density = 5.7g /23.5ml
Density = 0.24g/ml
Thus, the density of the piece of cork is 0.24g/ml
Answer:
a) R `= 3.5 ohms
b) energy decipated = 560J
Explanation:
V = I . R
R = V / I
R `= 70 / 20
R `= 3.5 ohms
2)energy decipated = 1/2ij²
energy decipated = 1/2 x 2.8 x (20)²
energy decipated = 560J
