Answer:
yes
Explanation:
Sugar can cause health problems.
I believe that sugar should be regulated by the government since it causes heath problems. As according to this website heathline.com that up to one third of the population in America is obese. As well as that regulating sugar will greatly help lowering that number, seeing that many food products have tons of sugar in them. By lowering the sugar and regulating it can cause less obesity among the average person in the US. As stated by HeathlyFoodAmerca.org consuming too much sugar can cause increased heath problems as shown, heart disease, diabetes, and teeth decay and this is why I believe that the U.S government should regulate sugar more.
Explanation:
Increasing the current intensity through the wire cannot increase the number of turns.
Thus, option B is the incorrect option.
Also, the current in the wire will depend on the power supply and not on the number of turns the wire has. The current in the wire will not change by increasing/decreasing the number of turns.
Thus, option C is the incorrect option.
The strength of the electromagnet depends on the intensity of the current. Thus, the current intensity will determine the electromagnetic strength and electromagnetic strength will not determine the current.
Thus, option D is the incorrect option.
The strength of the electromagnet depends upon the turns of wire around the metal core and the current or voltage passing through the wire. Thus, if we increase the number of turns around the metal core and the current or voltage is also increased, the strength of an electromagnet will also increase.
Thus the correct option is A.
Final Answer:
The correct option is A.
Answer:
The maximum value of the driving force is 1044.01 N.
Explanation:
Given that,
Weight of the object, W = 50 N
Force constant of the spring, k = 210 N/m
The system is undamped and is subjected to a harmonic driving force of frequency 11.5 Hz.
Amplitude, A = 4 cm
We need to find the maximum value of the driving force. The force is given by the product of mass and maximum acceleration as :
.....(1)
A is amplitude
m is mass,
is angular frequency
Angular frequency is given by :
Equation (1) becomes :
So, the maximum value of the driving force is 1044.01 N.
Answer:
C. Newton's First Law of Motion
Explanation:
As the car comes to an abrupt stop, the body is still moving forward, and is moved back by the seatbelt, an outside force. If not for the seatbelt, the body would continue forward until acted on by the car itself, or thrown out of the car.
