Answer:
Buwaya
Explanation:
Constellations are the patterns imagined by joining stars together. Ancient people used to imagine these patterns and further related the appearance of constellations with natural phenomenon. Similarly constellations can also be related with a particular season depending upon the visibility. For example, Orion signifies the start of the winters in Northern hemisphere.
The rainy season in Philippines starts in the month of June the same time when Buwaya (local name given to the box in Pegasus constellation) starts being seen in the sky after a brief period of disappearance from the sky.
Answer:
william h. seward secured the purchase of alaska from:
Explanation:
Explanation:
r^2= 9×10^9 × 5.87×5.87×10^-16 / 64.9
=47.7× 10^-8
so taking sq. root
r = 6.9 ×10^-4 m
or
r= 6.9×10^ -2 cm
this gives the required seperation
Given:
ΔT = 38 - 26 = 12°C, temperature change
Q = 11.3 J, heat input
c = 0.128 J/(g-°C), specific heat of lead
Let m = the mass of the lead.
Then
Q = m*c*ΔT
(m g)*(0.128 J/(g-°C))*(12 °C) = 11.3 J
1.536m = 11.3
m = 7.357 g
Answer: 7.36 g (2 sig. figs)
We are given the gravitational potential energy and the height of the ball and is asked in the problem to determine the mass of the ball. the formula to be followed is PE = mgh where g is the gravitational acceleration equal to 9.81 m/s^2. substituting, 58.8 J = m*9.8 m/s^2 * 30 m; m = 0.2 kg.
