Two players, Amy and also Beth, beat the adhering to game v a jug containing 100 pennies. The football player take transforms -- Amy walk first.
A tray of electronic components includes 15 components, 4 of which are defective. If 4 components are selected, what is the poss
To find various probabilities for the an option of components among eleven an excellent and 4 defective components, we will use the Combination.
12 grams that Iodine-13 was present 16 days ago
Amount that Iodine-131 sample current now = 3g
Amount the Iodine-131 sample present before 16 days = ?
W recognize that the half life the Iodine-131 is 8days
Let the amount of sample prior to 16 days it is in X
The X quantity Iodine-131 sample will decay ito ist fifty percent after 8 days
after 8 days
after following 8 days , i.e., 16 days
Now we understand that after 16 job we have actually 3 grams of Iodine-131 sample
X = 12
A 40-turn coil has a diameter that 11 cm. The coil is inserted in a spatially uniform magnetic ar of size 0.40 T so the the
(a) emf = 0.507 V
(b) emf = 0.0507 V
(c) emf = 0.00234 V
number of turns of the coil, N = 40 turns
diameter that the coil, d = 11 cm
radius the the coil, r = 5.5 centimeter = 0.055 m
magnitude of the magnetic field, B = 0.4 T
The size of the induced emf is calculation as;
(a) once the time, t = 0.3 s
(b) once the time, t = 3.0 s
(c) as soon as the time, t = 65 s
If a publication is knocked turn off a desk that is .75 m tall at a price of 2.0 m/s, how much away native the workdesk does it fall
wgc2010.org: 0.8 m
In the vertical direction, the rate is zero, u = 0.
Distance extended in the upright direction, s = 0.75 m.
The book would autumn with acceleration because of gravity in the upright direction, a = g = 9.8 m/s²
From the equation of motion,
s = u t + 0.5 a t²
Substituting the over values, us will discover out the time taken for the publication to struggle the ground.
⇒0.75 m=0+0.5×9.8 m/s²×t²
⇒t = √0.153 = 0.39 s ≈ 0.40 s
Now, the horizontal distance covered,
d = v×t ⇒d= 2.0 m/s × 0.40 s =0.8 m
Hence, the publication falls 0.8 m far from the desk.
