The half-life of radium-226 is 1600 years. How many
grams of a 7 g sample will remain after 3200 years?
SHOWALL STEPS TO SOLVE THE PROBLEM
Answer:
1600 years half life
3200/1600 is 2 half lifes
first half life takes the sample to 1/2 it's original amount and the second takes it to 1/4 of it's original amount
so 1/4*7gm is 1.75gm

A bicyclist steadily speeds up from rest to 11.0m/s during a 5.50s time interval. Determine all unknowns and answer the following questions. What is the magnitude of the bicyclist's acceleration? How far did the bicyclist travel during this time?
Explanation:
acceleration is 2 m/s^2
v-u/t
distance travelled is 30.25 meter
(v^2-u^2)/2a
11*11/2*2
121/4
30.25 m
The acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.
We have a bicyclist.
We have to calculate the acceleration and the total distance travelled by the bicyclist.
State the three equations of motion.The three equations of motion are -
v = u + at
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
v² - u² = 2aS
According to the question -
u = 0 m/s
v = 11 m/s
t = 5.5 s
Therefore -
For acceleration -
v = u + at
On solving -
11 = 0 + 5.5 a
5.5a = 11
a = 11 / 5.5 = 2 m/s²
For total distance covered -
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
On solving -
S = 0 + 0.5 x 2 x 5.5 x 5.5 = 30.25 meters.
Hence, the acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.

Calculate the running costs of a filament lamp with a 60 W bulb and a CFL lamp with a 15 W bulb for 15 hours.
1 kWh costs 10p.
cost = power (kW) × time (hours) × price (per kWh)
Answer:
the cost of running the bulbs is 11.25p
Explanation:
Given;
cost of running 1 kwh = 10 p
power of filament bulb, P = 60 W
power of the CFL bulb, P = 15 W
time of power consumption, t = 15 hours
Total Energy consumed;
E = (60W + 15W) x 15 hours
E = (75)(15)
E = 1125 Wh
E = 1.125 kWh
Cost of 1.125 kWh = 1.125 x 10p
= 11.25p
Therefore, the cost of running the bulbs is 11.25p

1. Determination of the mass of gasoline
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Mathematically, the density of a substance can be expressed as:
Density = mass / volume
With the above formula, we can obtain the mass of the gasoline as follow:
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
Density = mass / volume
0.7 = Mass of gasoline / 15
Cross multiply
Mass of gasoline = 0.7 × 15
Mass of gasoline = 10.5 Kg
2. Density has various units some are listed below:
I. Kilogram per litre (Kg/L)
II. Kilogram per cubic metre (Kg/m³)
III. Milligram per millilitre (mg/mL)
IV. Gram per millilitre (g/mL)
V. Gram per cubic centimetre (g/cm³)
Considering the options given in the question above, it is evident that second per gram (s/g) is not a unit of density because density is mass per unit volume.

A train moves at 300 km/h. How far will it go in 5 hours?
Answer:
1,500 km
Explanation:
300 km/h
300 kilometers PER HOUR
So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.
300 * 5 = 1,500
The train moves at 1,500 km in 5 hours.
