In the early universe and in stars, deuterium nuclei are produced from the combination of one proton and one neutron, with the r

poizon [28]

Answer:

$Q = q_e = 1.6 \times 10^{-19} C$

Explanation:

As we know that charge is always conserved

so here we have

initial total charge = final total charge

also we know that gamma rays are chargeless and massless particles

so we have

charge on deuterium is given as

Q = charge on proton + charge on neutron - charge on gamma

so we have

$Q = 1.6 \times 10^{-19}$

$Q = q_e = 1.6 \times 10^{-19} C$

An area where a mantle plume allows magma to burst through a tectonic plate NOT near a boundary is ______________.

aleksandr82 [10.1K]

I don't know the answer but I do know this
A mantle plume is posited to exist where hot rock nucleates at the core-mantle boundary and rises through the Earth's mantle becoming a diapir in the Earth's crust.[3] The currently active volcanic centers are known as "hot spots". In particular, the concept that mantle plumes are fixed relative to one another, and anchored at the core-mantle boundary, was thought to provide a natural explanation for the time-progressive chains of older volcanoes seen extending out from some such hot spots, such as the Hawaiian–Emperor seamount chain.

Answer:

The answer to your question is: D) Ф₂ = 49.71°

Explanation:

Data

n₁ = 1.33

Ф₁ = 35°C

n₂ = 1

Ф₂ = sin⁻¹ (n₁ sinФ₁/n₂)

Process

Substitution

Ф₂ = sin⁻¹ (n₁ sinФ₁/n₂)

Ф₂ = sin⁻¹ (1.33 sin 35/1)

Ф₂ = sin⁻¹ (1.33 x 0.574/ 1)

Ф₂ = sin⁻¹ ( 0.7628 / 1)

Ф₂ = sin⁻¹ (0.7628)

Ф₂ = 49.71°

Larger animals have sturdier bones than smaller animals. A mouse's skeleton is only a few percent of its body weight, compared t

Rama09 [41]

Answer:

$a_s=4.8\times 10^{-2}~m^2$

Explanation:

Given:

cross sectional area of the bone, $a=4.8 \times 10^{-4} ~m^2$

factor of up-scaling the dimensions, $s=10$

Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.

The scaled up area is:

$a_s=a\times s^2$

$a_s=[4.8 \times 10^{-4}]\times 10^2$

$a_s=4.8\times 10^{-2}~m^2$
