I think everytime they swim away, the water pushes the enemy back, which makes the octopus go faster. Every action has an equal and opposite reaction. Hope this helps.
The correct option is (D). i.e.<span>When the current is too high, a metal strip in the fuse melts and opens the circuit.
Explanation: </span>The fuse contains a small piece of wire which has very less melting point. As there is huge current flow, the wire heats to the heavy current flow & melts & the circuit is broken.
Hence, it saves the device from the heavy current flow & the device is damage free. breaks the circuit if a fault in an appliance causes too much current flow.
Answer:
-107 m
Explanation:
Sum of forces in the y direction:
∑F = ma
-qE = ma
a = -qE/m
a = -(1.60×10⁻¹⁹ C) (304 N/C) / (9.11×10⁻³¹ kg)
a = -53.4×10¹² m/s²
Given in the y direction:
v₀ = 0 m/s
a = -53.4×10¹² m/s²
t = 2×10⁻⁶ s
Find: Δy
Δy = v₀ t + ½ at²
Δy = (0 m/s) (2×10⁻⁶ s) + ½ (-53.4×10¹² m/s²) (2×10⁻⁶ s)²
Δy = -107 m
