Answer:
R = 73.25 m
Explanation:
We have,
Initial speed of the ball is 27 m/s
It is projected at an angle of 40 degrees
The maximum range of the ball is given by :
Plugging all the values we get :
So, the maximum range of the ball is 73.25 m
Answer:
Plate B will have a higher capacitance
Explanation:
One of the conditions affecting the capacitance of a capacitor is spacing between plates, the greater the spacing the lesser the capacitance and vice versa.
Hence plate B will have the B will have higher capacitance since the spacing is less when compared with that of plate A
Answer: 10kg
Explanation:
Given that:
Kinetic energy of puppy = 245J
Velocity of puppy = 7 m/s
mass of puppy = ?
Recall that kinetic energy is the energy possessed by a moving body. It is measured in joules, and depends on the mass and velocity of the moving body
i.e K.E = 1/2 x mass x (velocity)^2
245J = 1/2 x mass x (7 m/s)^2
245 = 0.5 x mass x 49
245 = 24.5 x mass
Mass = 245/24.5
Mass = 10kg
Thus, the mass of the puppy is 10kg
Answer: Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.
