If the mass of an object doubles and the force remains the same, what happens to the acceleration? A. Doubles B. Halves C. Remains the same D. Quadruples 相关知识点: 试题来源: 解析 B。原因:根据牛顿第二定律 F = ma,当 F 不变,m 变为原来的两倍时,a 变为原来的一半。
The force exerted by a ramp on a mass increases as the angle of the ramp increases. This is because the steeper the angle, the more the weight of the object is directed perpendicular to the ramp surface, resulting in a larger normal force. Does the mass of the object affect the force ...
What happens when the mass increases? What is the difference between charging by conduction and charging by induction? Explain about induced and reduced charges. Describe what is happening to the resistance of a light bulb as the voltage increases? If a conducto...
You can also lose weight by living on the moon, but again your mass is the same. In physics, mass is defined as the amount of force required to cause a body to accelerate. Mass is very closely related to energy in physics. Mass is dependent on the body's motion relative to the ...
An object of mass 10 kg is accelerated by a force of 20 N. What is the acceleration of the object? A. 2 m/s² B. 3 m/s² C. 4 m/s² D. 5 m/s² 相关知识点: 试题来源: 解析 A。根据牛顿第二定律 F=ma,可得加速度 a=F/m=20/10=2m/s²。反馈 收藏 ...
ALOS-3. This time they are carrying a mass simulator, “Vehicle Evaluation Payload 4,” with two cubesats. JAXA will webcast the launch. Some call this the third launch attempt, counting the February scrub as the first and the March failure as the second, but we don’t count the scrub ...
Oslo, Norway – July 1, 2024 – Opera GX, the browser for gamers, is bringing a significant update to the browser’s built-in AI, Aria. This update provides users with the latest AI features that Opera has been releasing as part of their experimental AI Feature Drops program in the Deve...

The second stage is to achieve coordinated development between rural economic development and the rural ecological environment. According to the Environmental Kuznets curve, when the economic development level of a region increases to a certain extent, the degree of environmental pollution will continue ...
The concept of supply and demand is fairly straightforward. As demand increases (or supply decreases) the price should go up. As demand decreases (or supply increases) the price should go down. Sounds simple? Not quite. The price of oil as we know it is actually set in the oilfuturesmark...
