Answer:
change that a lead is 0.13533
Explanation:
µ = 50000
f(t) = [e^(-t/µ )]/[µ if t ≥ 0
f(t) = 0 if t < 0
τ = 100000
to find out
the chance that a led will last
solution
we know function is f(t) = [e^(-τ/µ)]/[µ]
τ = 100000
so we can say that probability (τ ≥ 100000 ) that is
= 1 - Probability ( τ ≤ 100000 )
that is function of F so
= 1 - f ( 100000 )
that will be
= 1 - ( 1 - [e^(-τ/µ)]/[µ] )
put all value here τ = 100000 and µ = 50000
= 1 - ( 1 - [e^(-100000/50000)] )
= 1 - 1 - [e^(-100000/50000)]
= 0.13533
so that change that a lead is 0.13533
Answer: Mars has lower gravity and lower magma buoyancy
Explanation: The gravity in mars is low. Low gravity affect the occurrence of volcanic eruptions. The buoyancy of the magma in Mars is lower and the depth of the magma chamber deeper (Buoyancy is the difference in density between the surrounding crust and the magma ascending for eruption). Olympus Mons which is larger and wider than mount Everest was formed as a result of overcoming of the low gravity and buoyancy by the magma to release enormous volume of magma to the surface.
Another reason why the volcanoes on Mars are so large is because the crust on Mars is static unlike Earth.
Answer:
A and C
Explanation:
Helioseismology is a branch of science that makes use of differential rotation and magnetic field to study he structure of the sun.
A filtergram represents the photo of the surface of the sun that is made using high energy particles being accelerated by the sun's magnetic field. <em>Hence, it can only be used to study the surface and not the layers below the photosphere.</em>
The chromosphere of the sun has a temperature between 6,000 °C to about 20,000°C while the photosphere has a temperature between 4,230 and 5,730 °C.<em> Hence, the chromosphere has a higher temperature.</em>
The only true options are A and C.
Answer:
Without plants producing oxygen, no creatures would be able to breath and would thus die off. With no creatures breathing, and thus producing no carbon dioxide, plants would starve off and die since they require carbon dioxide to live.
Explanation:
Number 20 is B and 21 is C
