The strength of an electromagnet can be altered by increasing the number of coils around the core. The more times the coil is wrapped, the stronger the electromagnet is.
Your answer is: B) Increasing the number of coils around the core
Have an amazing day and stay hopeful!
Answer:
A. Their shape
Explanation:
The name clearly shows that the shape of these canals are semi-circular. The semi-circular canals consist of three tubes filled with fluid and located in the inner ear. They help to maintain balance and transmit impulses through the movement of the fluids. The impulses sent through these fluids are sent to the brain for interpretation.
The function of the canals are not indicated by the name, rather the shape is hinted through the name.
Answer:
46°C
Explanation:
q = mCΔT
336,000 J = (20 kg) (4200 J/kg/°C) (50°C − T)
T = 46°C
Answer:
The answer is 0.47 watts
power is calculated by Work/Time
14/30 =0.46666666 which is approximately 0.47watts
The mass of the van will be 2.5 kg, Mass is found as the ratio of the force and the acceleration.
<h3>What is force?</h3>
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body.
Force is defined as the product of mass and acceleration. Its unit is Newton.
F=ma
5.5 kN = m × 2.2m/s²
m= 2.5 kg
Hence,the mass of the van will be 2.5 kg,
