Answer:
Option C. ⁰₊₁e
Explanation:
From the question given above, the following data were obtained:
¹⁵₈O —> ¹⁵₇N + __
Let the unknown be ʸₓM
Thus, the equation becomes
¹⁵₈O —> ¹⁵₇N + ʸₓM
Next, we shall determine x, y and M. This can be obtained as follow:
8 = 7 + x
Collect like terms
8 – 7 = x
1 = x
x = 1
15 = 15 + y
Collect like terms
15 – 15 = y
0 = y
y = 0
ʸₓM => ⁰₁M => ⁰₊₁e
Therefore,
¹⁵₈O —> ¹⁵₇N + ʸₓM
¹⁵₈O —> ¹⁵₇N + ⁰₊₁e
Answer:
45.9m
Explanation:
Given parameters:
Final velocity = 30m/s
Initial velocity = 0m/s
Unknown:
Height of fall = ?
Solution:
The motion equation to solve this problem is given below;
V² = U² + 2gH
V² = 0 + (2 x 9.8 x H)
30² = 19.6H
H =
= 45.9m
Answer:
Explanation:
The problem is based on vibration in string .For it the formula is as follows :
n = k √T , n is frequency of fundamental tone , k is constant for a string of given length and T is tension in the string .
In the first case weight of sphere is equal to tension .
weight = volume of sphere x density of copper x g
= v x 8960 x g
Putting the values
300 = k √ (v x 8960 x g)
300 = k √ 87808v
When the sphere is half submerged
tension is equal to apparent weight of sphere in water
= v x 8960 x g - .5 v x 1000 x 9.8 , v is volume
= 82908v
for second case
n = k √ 82908v
dividing the two equations
n / 300 = 
= .9716
n = 291.5 Hz .

Please rephrase the question. Thanks!
You should turn left and must yield to oncoming vehicles going straight.
Left turns must give way to oncoming traffic. A four-way stop allows the first driver to reach the intersection ahead of the other drivers after coming to a complete stop. Drivers entering the driveway from a driveway alley or curb must yield to vehicles already on the main road.
Gradually decelerate while looking in the rearview mirror. Transfer to the left lane. Watch out for oncoming vehicles and pedestrians. A green light means GO but you must let any remaining vehicles bicycles, or pedestrians at the intersection pass before you can proceed. You can turn left only if there is enough room for oncoming traffic bicyclists or pedestrians to turn before it becomes dangerous.
