9. How long will it take 120 grams of Strontium-90 to decay to 7.5 grams?
with steps pls
Answer:
116 years
Explanation:
To solve this, we will use the half life equation;
A(t) = A_o(½)^(t/t_½)
Where;
A(t) is the amount of strontium left after t years;
A_o is the initial quantity of strontium that will undergo decay;
t_½ is the half-life of strontium
t is the time it will take to decay
We are given;
A(t) = 7.5 g
A_o = 120 g
From online values, half life of strontium-90 is 29 years. Thus, t_½ = 29
Thus;
7.5 = 120 × ½^(t/29)
Divide both sides by 120 to get;
7.5/120 = ½^(t/29)
0.0625 = ½^(t/29)
In 0.0625 = (t/29) In ½
-2.772589 = (t/29) × (-0.693147)
(t/29) = -2.772589/(-0.693147)
t/29 = 4
t = 29 × 4
t = 116 years

Which kind of worm has a closed circulatory system?
a planarian
a fluke
a pinworm
an earthworm
An earthworm has a closed circulatory system.
The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm.
As important as they are alive for distributing nutrients and organisms and decomposing matter, worms are also very important in the food chain. They provide a crucial protein-rich source of food for other important species like birds, hedgehogs and frogs.
They may live up to eight years, though one to two is more likely. Full size for an earthworm varies among species, ranging from less than half an inch long to nearly 10 feet.

How many moles are present in 5.24 x 1023 molecules of CH4?
Answer:
0.807 moles
Explanation:
No of molecules = No of mole × Avogadro's number
No of mole = No of molecules / Avogadro's number
No of mole = 5.24×10^23/6.02×10^23
0.870 moles
18. Which statement about photosynthesis is FALSE?
a
Tilmy green pigment chlorophyll captures light
energy
b Oxygen is needed as a reactant to produce
glucose
The process converts light energy from the
csun into chemical energy in the bonds of
glucose.
d
Carbon dioxide is needed as a reactant to
produce glucose.
Which statement about photosynthesis is FALSE?
Answer:
b. Oxygen is needed as a reactant to produce
glucose is the incorrect statement here
Explanation:
plants uses simple raw materials to prepare their food , which includes water ( H2O ) and Carbon dioxide ( CO2 ).
and traps sunlight by Green pigments known as chlorophyll and stores these energy in bonds of glucose molecules
so ,
after this reaction glucose and oxygen is formed as products
● hence we conclude that Oxygen is not needed as a reactant to produce glucose , oxygen is the bi product formed during photosynthesis.

Why are summer days longer than winter days on Earth?
A. During the summer, Earth's rotational axis is parallel to the Sun's rotational axis.
B. During the summer, Earth is at the point in its orbit when it is closest to the Sun.
C. The region of Earth experiencing summer rotates past the Sun more slowly than the region experiencing winter.
D. The region of Earth experiencing summer is tilted toward the Sun while the region experiencing winter is tilted away from the Sun.
PLEASE HELP ITS A TEST
Answer:
A. During the summer, Earth's rotational axis is parallel to the Sun's rotational axis.
Explanation:
Actually, though, the Earth is tilted 23.4 degrees! (A circle is 360 degrees.) This tilt is the reason that days are longer in the summer and shorter in the winter. The hemisphere that's tilted closest to the Sun has the longest, brightest days because it gets more direct light from the Sun's rays.
Plz mark me brainliest if correct :)
During summer days, north pole of earth is exposed to sun because ofthe tilt of earth's rotational axis. Thus, The region of Earth experiencing summer is tilted toward the Sun while the region experiencing winter is tilted away from the Sun.
What is summer?Summer is a season in earth. There are different seasons in earth namely, summer, winter, spring, autumn etc. These season are arising due the revolution of earth around sun.
The distance of different regions of earth from sun changes due to the revolution of earth. Thus heat gained by these regions will be different in different seasons.
The north pole in summer gains more heat and light energy because of tilt in the axis of earth is towards the sun. Hence, the day time will be longer in summer than the winter. In winter, the earth is relatively apart from sun and thus tilt is and gains less light and heat .

Someone please answer this...
Answer:
5446.8 J
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 50 g
Initial temperature (T₁) = 70 °C
Final temperature (T₂) = 192.4 °C
Specific heat capacity (C) = 0.89 J/gºC
Heat (Q) required =?
Next, we shall determine the change in the temperature. This can be obtained as follow:
Initial temperature (T₁) = 70 °C
Final temperature (T₂) = 192.4 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 192.4 – 70
ΔT = 122.4 °C
Finally, we shall determine the heat required to heat up the block of aluminum as follow:
Mass (M) = 50 g
Specific heat capacity (C) = 0.89 J/gºC
Change in temperature (ΔT) = 122.4 °C
Heat (Q) required =?
Q = MCΔT
Q = 50 × 0.89 × 122.4
Q = 5446.8 J
Thus, the heat required to heat up the block of aluminum is 5446.8 J
