1.) temperature change, 2.) color change, 3.) gas formation
Answer:
Given that,
- Power = 2000 W
- time = 60 seconds
- distance= 10m
Power = work done ÷ time
Here, since the movement is vertical, w = mgh
So,
Power = mgh÷t
2000 = (m × 9.8 ×10) ÷ 60
m = (2000 ×60) ÷98
m = 1224.5kg
Answer:
0.266 m
Explanation:
Assuming the lump of patty is 3 Kg then applying the principal of conservation of linear momentum,
P= mv where p is momentum, m is mass and v is the speed of an object. In this case
where sunscripts p and b represent putty and block respectively, c is common velocity.
Substituting the given values then
3*8=v(15+3)
V=24/18=1.33 m/s
The resultant kinetic energy is transferred to spring hence we apply the law of conservation of energy
where k is spring constant and x is the compression of spring. Substituting the given values then
For energy producing reactions they need Hydrogen atoms, heat, and pressure for the experiments.
<u>Explanation:</u>
The initial step of the Hydrogen combination process: a core of Deuterium (2H) is shaped from two protons with the discharge of an antielectron and a neutrino. In the fundamental Hydrogen combination cycle, four Hydrogen cores (protons) meet up to make a Helium core.
An atomic combination response is characterized as the response wherein at least two lighter cores consolidate together to shape heavier cores with the arrival of high measures of vitality.
Combination can possibly give the sort of baseload vitality expected to give power to our urban communities and our enterprises. Maintainability: Fusion powers are generally accessible and almost limitless.
Answer:
A) 2.09
B) -62.09°
Explanation:
If D = A+B+C then C = D - A - B
Converting both A and B to rectangular coordinates, we get:
A = [-4.07 , 4.68] and B = [6.19 , 3.87]
Replacing these values we can get the x and y components of C:
C = [0.98 , -1.85]
Its module is:
Its angle is:
