Answer:
the ball will go up 3s and down 3s
v=gt
where t=3s and g=9.8m/s^2
distance=v0(t)+(1/2)gt^2
where initial velocity (v0)=0
Explanation:
Answer:
0.25 kg m^2
Explanation:
mass of each , m = 500 g = 0.5 kg
distance, r = 50 cm = 0.5 m
Moment of inertia about the axis passing through one corner and perpendicular to the plane of triangle
I = mr^2 + mr^2
I = 2 mr^2
I = 2 x 0.5 x 0.5 x 0.5
I = 0.25 kgm^2
The heat energy the surrounding air gained is <u>755 j.</u>
Energy is a quantitative property given to a body or physical system and can be identified as work being done in the form of heat and light. Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed. Energy is the ability to do work. It can exist in electrical, kinetic, thermal, electrical, chemical, nuclear, or other forms.
<u>Concept:-</u>
Since the energy is always conserved, the energy lost by the hot water is gained bt the surrounding
- energy lost = + energy gained by the surrounding
- 755 j = + <u>755 j</u>
<u />
Energy exists in many forms. Examples include light energy, thermal energy, mechanical energy, gravitational energy, electrical energy, acoustic energy, chemical energy, and nuclear or atomic energy. Each form can be transformed or changed into other forms.

Answer:
Image result for Why does the Moon appear red during a lunar eclipse?
A lunar eclipse takes place when the sun, Earth and moon line up in space. The moon passes through Earth's shadow. ... Bottom line: The moon can look red during a total lunar eclipse because of sunlight that's filtered and refracted by Earth's atmosphere
