Answer: Bases are slippery.
Explanation:
Bases and acids can be determined by the amount of hydrogen or hydroxide ions in each solution. If a solution has more hydrogen ions than hydroxide ions, it is acidic, whereas if it has more hydroxide ions than hydrogen ions, it is basic.
Using a litmus paper test for a acidic/basic solution, the paper will turn different colors. In an acidic solution, paper will turn red, but in a basic solution, paper will turn blue.
Bases, compared to acids, feel slippery on the skin because they interact with fatty acids on the skin. Comparatively, acids feel sticky.
Acids taste sour. Think of an acid like lemon juice, compared to bases, which taste bitter (blood, for example)
Answer:
The shortest transverse distance between a maximum and a minimum of the wave is 0.1638 m.
Explanation:
Given that,
Amplitude = 0.08190 m
Frequency = 2.29 Hz
Wavelength = 1.87 m
(a). We need to calculate the shortest transverse distance between a maximum and a minimum of the wave
Using formula of distance
Where, d = distance
A = amplitude
Put the value into the formula
Hence, The shortest transverse distance between a maximum and a minimum of the wave is 0.1638 m.
Answer:
213.18 volt
Explanation:
N = 500, A = 0.02 m^2, B = 0.30 T, f = 960 rpm = 960 / 60 = 16 rps
The maximum value of induced emf is given by
e0 = N x B x A x ω
e0 = N x B x A x 2 x π x f
e0 = 500 x 0.3 x 0.02 x 2 x 3.14 x 16
e0 = 301.44 Volt
The rms value of induced emf is given by
e rms = 213.18 volt
Answer:
A)
Explanation:
Once released, the projectile is subject only to the influence of gravity, which is always downward, and produces on the object an acceleration of 9.8 m/s².
The vertical acceleration of the rocket only supplies an initial velocity to the projectile, in the vertical direction, upwards.
