Answer 2

It looks like you're asking about a physics problem involving energy (Q), a given quantity (q), and mass (m). However, the formatting and notation are a bit unclear. Let me try to interpret and solve the problem.

Assuming:

• Q is the energy in kilojoules (kJ), where Q = 50,000 kJ (50,000 kilojoules).
• q is a given quantity in scientific notation, where q = 1 × 10^7.

We're trying to find the mass (m).

In physics, the relationship between energy (Q), mass (m), and a constant (c) can be represented using the formula:

$Q = mc^2$

where:

• Q is the energy in joules (J),
• m is the mass in kilograms (kg),
• c is the speed of light in a vacuum, approximately $3.00 × 10^8 \, \text{m/s}$.

To convert Q from kilojoules (kJ) to joules (J), we need to multiply by 1,000 (1 kJ = 1,000 J). So, Q in joules is:

$Q = 50,000 \times 1,000 \, \text{J} = 50,000,000 \, \text{J}$

Given that q is given in scientific notation as $1 \times 10^7$, we can express q in regular notation:

$q = 1 \times 10^7 = 10,000,000 \, \text{J}$

Now, we can equate Q and q:

$Q = q$ $50,000,000 \, \text{J} = 10,000,000 \, \text{J}$

Now, we can solve for the mass (m):

$m = \frac{Q}{c^2}$

$m = \frac{50,000,000 \, \text{J}}{(3.00 \times 10^8 \, \text{m/s})^2}$

Let's calculate m:

$m \approx \frac{50,000,000 \, \text{J}}{9.00 \times 10^{16} \, \text{m}^2/\text{s}^2}$ $m \approx 5.56 \times 10^{-10} \, \text{kg}$

So, the mass (m) is approximately $5.56 \times 10^{-10}$ kilograms.
