Answer:
<h2>5.3N</h2>
Explanation:
Step one:
given data
mass of bullfrog= 0.54kg
Step two:
Required
The force F in Newton
From newton first law
F=mg
The acceleration due to gravity acting on the frog is 9.81m/s^2
hence
F=0.54*9.81
F=5.3N
The normal force is 5.3N
Answer:
who you ganna throw that rock at child
Explanation:
Time is being measured in days here so if you want to calculate the rate of increase after one day, substitute 1 for t in your rate equation:
dB/dt = 0.677598 cos(1.232(1))
dB/dt = 0.22
Explanation:
Hipparchus had observed and discovered the precession motion of Earth. Due to the precession the axis of the Earth will gradual shift in a cycle of 25772 years. That means the axis will point towards different stars in the celestial sphere and our pole stars will change.
Because of this change in the axis the apparent position of Sun with respect to the background constellation (sun signs) regresses. Because of which the dates associated with the sun signs will be wrong.
Answer:
Explanation:
Current in a wire is 120mA
I = 120mA = 120 × 10^-3 A
I = 0.12 A
If the voltage applied at across the wire is tripled
From ohms law
V=IR
R = V / I
Since R is constant
Then,
V / I = K
Then, we can say
V / I = V' / I'
Given that,
Initially
V = V and I = 120mA
Then, V' = 3V and I' =?
So,
V / I = V' / I'
V / 120 = 3V / I'
Cross multiply
V × I' = 120 × 3V
Divide both sides by V
I' = 120 × 3V / V
I' = 360mA
So, the current in the wire when the voltage was tripled is 360mA, the current was also tripled
