Answer:Cross-pollination is two plants that work together to pollinate and self-pollinate is when a flower pollinates itself. ... Why do you think plants surround the seeds with a yummy fruit? To protect the seeds so that they can reproduce. How is cross-pollination different from self-pollination?
Explanation:
Answer:
Explanation:
x = 2 cos wt = 2 cos 10t ; w = 10
velocity = dx/dt = -2 x 10 sin 10 t.=- 20 sin 10t
t = .4
velocity = -20 sin 10 x .4 = -20 sin 4 = -20 x -0.7568 = 15.136 cm /s
w = √ k / m = 10 = √ k / .05
k = 15.136 N/m
Answer:
v = 225 m/s
Explanation:
Given,
The momentum of the spaceship, p = mv = 45,000 Kg m/s
The mass of the spaceship, m = 200 Kg
The velocity of the spaceship, v = ?
The relationship between the momentum, mass, and velocity is given by the formula
p = mv Kg m/s
Therefore,
v = p/m m/s
Substituting the values in the above equation
v = 45,000 Kg m/s / 200 Kg
= 225 m/s
Hence, the magnitude of velocity of the spaceship is, v = 225 m/s
32.6% of 1.4 Mw
= (0.326) x (1,400,000 joules/second)
= 456,400 joules/second .
1 year
= (365 da) x (86,400 sec/da) = 31,536,000 seconds
(456,000 joules/sec) x (31,536,000 sec) = 1.438 x 10¹³ Joules
(That's 1.438 x 10⁷ Megajoules, or 3,994,560 kWh)
