Answer:
Explanation:
i. CW moment = 10 N (10 cm) + 30 N (30 cm) - 60 N (40 cm) = - 1400 N-cm
ii. ACW momenet = 60 N (40 cm) - 10 N (10 cm) + 30 N (30 cm) = 1400 N-cm
iii. No. The lever is not balanced in the situation. Because the moment is ± 1400 N-cm. if balance, the moment must be Zero.
iv. the location of 10N by keeping the other loads unchanged to balance the lever is 150 cm
take moment from Δ (support)
60(40) = 10(x) + 30(30)
2400 = 10x + 900
10x = 2400 - 900
10x = 1500
x = 1500/10
x = 150 cm
therefore, the location of 10N by keeping the other loads unchanged to balance the lever is 150 cm
Explanation:
In Europe the standard voltage in homes is 220 V instead of the 120 V used in the United States.
100-W European bulb would be intended for use with a 220-V potential difference.
(a) If V = 220 V and P = 100 W
Power :
If you bring a "100-W" European bulb home to the untied States, what should be its US power rating. So,
or
P = 29.8 watts
(b) Let I is the current will the 100-W European bulb draw in normal use in the United States. So,
Hence, this is the required solution.

Explanation:
Chemical Digestion of Carbohydrates, Proteins, Lipids, and Nucleic Acids. The chemical breakdown of the macromolecules contained in food is completed by various enzymes produced in the digestive system.
velocity and wavelength are likely to change in the process
- When a wave travels from one medium to another it undergoes a change in direction and this is referred to as refraction.
- Refraction is the bending of a wave or a change in direction of a wave as it travels from one medium to another. Refraction is accompanied by change in velocity and wavelength of a wave

Yes. Here is my explaination: Peer pressure is a complicated area. On one hand, it can help your child develop the coping skills necessary for adulthood. It can also, however, lead them in bad directions. While teens may feel they have “grown up,” their brains are not finished developing and one of the immature functions is judgment. Peer pressure might encourage teens to become more active in athletics or to avoid risky behaviors. Or it could lead them to try alcohol or drugs, skip school or engage in other negative behaviors.
