a man walking at the rate of 5km/hr crosses a bridge in 15 min find the length of the bridge in meyers​
Westkost [7]

Answer:

I hope this helps. Plzz mark as brainliest

Explanation:

A man walking at the rate of 5 km/hr. crosses a bridge in 15 minutes. The length of the bridge (in meters) is:

[A]1000 m

[B]1250 m

[C]600 m

[D]750 m

1250 m

Speed of the man = 5 km/hr



Time taken to cross the bridge = 15 minutes

Length of the bridge = Speed  Time



Hence option [B] is the right answer.

Star X has an apparent magnitude of 1. Star Y has an apparent magnitude of 4. Both stars are in the same star cluster. Which sta
sashaice [31]

Answer:

Explanation:

From the given information:

Since both stars are in the same cluster, the magnitude and luminosity relationship can be calculated as:

m_1 - m_2 = -2.5 log _{10} (\dfrac{L_1}{L_2})

Given that;

m_1 = 1 and

m_2 = 4

Therefore,

1 - 4 = -2.5 log _{10} ( \dfrac{L_1}{L_2})

3 = -2.5 log _{10} ( \dfrac{L_1}{L_2})

Making \dfrac{L_1}{L_2} the subject of the formula:

\implies \dfrac{L_1}{L_2}= 10^{(\dfrac{3}{2.5})}

=15.84

≅ 16

Hence, we can conclude that star X is more luminous by a factor of 16
