⑴ 英語作文:描述一個物理實驗的過程和結果
Objective: To study the imaging characteristics of convex mirror and concave mirror
Laboratory equipment: metal spoon (spoon)
Experimental process: 1, with the back of the spoon when the mirror according to their own.
2, with the front of the spoon when the mirror according to their own.
3, with the front of the spoon as a mirror pencil head.
Experimental phenomenon: the first step to see is their own legislation is like a narrow
The second step is to see their own inverted figure.
The third step to see the pencil downside down the image, but narrow the distance between the pencil and the spoon can see the inverted magnified image, further narrowing their distance can see the positive magnified image.
⑵ 用英語表達簡單的物理實驗過程
Take a cup, fill three quarter of it with water, cover the cup with a piece of paper, then turn it over. the paper will not fall. this shows that the atmospheric pressure outside and inside of the cup is the same.
⑶ 英文物理,要英文答案,謝謝
1. How much heat is required to heat 1 kg of ice at --‐10 oC until it becomes 1 kg of steam at 110oC? (Be sure to show all your work!)
ANSWER:
Q=CMΔt
1kg of ice from -10°C to 0°C
Cice=2100J/(kg.℃)
Q1=2100×1×10=21000J
Cwater=4200J/(kg.℃)
Q2=4200×1×110=462000J
Q=Q1+Q2=483000J
背景知識:(一)物質有三態,即固態、液態、氣態,當固態變成液態時,因溶解而吸收熱量。當液態變為氣態時,因蒸發而吸收熱量。或由固態不經由液態,直接變成氣態時,因升華而吸收熱量,這些溶解、蒸發、升華過程皆會吸收熱量而降低物質或空間的熱量,產生凍或冷藏或冷氣的效果。反之,若物質由氣態變成液態時,因液化而排出熱量,或由液態變為固態,因凝固而排放熱量,這些液化或凝固過程皆會排放熱量而提高物質或空間的溫度產生加熱或暖氣效果。
2. In your own words, describe a situation where heat is transferred in each of the following mechanisms: conction, convection, radiation.
ANSWER:
1 conction is the flow of internal energy from a place of higher temperature to one of lower temperature by the interaction of the adjacent objects in the intervening space.
2 convection is the transfer of internal energy in or out of an object by the physical movement of a surrounding fluid that transfers the internal energy along with its mass.
3 radiation is the transfer of internal energy via electromagnetic waves. For most bodies on the earth, this radiation lies in the infrared region of the electromagnetic spectrum.
All the conception above shows that heat transfer can only taken from high temperature to low temperature without any work.
背景知識:熱量的傳遞,藉由傳導、對流、輻射三方式,由高溫處往低溫處流動,若需要將低溫處之熱量往高溫處搬移,則需輸入外力以作功,就如冷凍循環系統需由壓縮機作功,將低溫處之熱量搬移至高溫處散熱。

⑸ 誰能幫我用英語翻譯一篇物理現象!
2.在地上放塊矩形石板,板上四個直角處分別放上1個雞蛋,4個雞蛋支撐著一本書,書上再放3塊磚,磚上再放1塊瓦,然後要一個人用錘子去敲瓦,問:蛋碎瓦全還是瓦碎蛋全?
如果石板面積足夠大,書足夠大,書還能撐起3塊磚,磚和瓦不是用來造長城的質量,錘子足夠硬,撞擊端面沒有緩沖,掄錘者有一定的胸口碎大石技巧,我想瓦還是有可能碎的,磚可能會掉灰,雞蛋嘛,可能也會碎,取決於書的緩沖作用。。。就這些了,不過沒這么放的。

⑹ 怎麼用英語解答物理
Solutions(解答):
(當A為1m/s時):For A=1m/s, (則B為2m/s) :Then B=2m/s,
(而且……) :and …… (或者……) :or ……
(所以 ……) :so(that) …… (如果……) :if……
(假設……) :assume…… (從方程/式子1、3) :from equation 1、3
(定義……) :define …… (式子1變為) :equation 1 becomes……
(式子中的A=2) :where A=2
還有一些表達:we(would) have ,we obtain ,we can write ,we find ,which等等
實在不會寫的直接寫個 then 然後列下面的方程或式子。
只要表述清楚解題過程和結果就行,畢竟不是寫論文
⑺ 如何介紹物理這一學科,用英語
你要高中的還是初中的
給你個大綱吧:首先開個頭,告訴大家物理是一門什麼樣的課 難不難學之類的簡單的隨意的開頭 但是要記住扣題
第二段開始介紹物理課有哪些內容 具體點 比如有力學 電學 電磁場 等等 再說說你對它的看法 覺得有些內容如何如何 有些如何如何
第三段扣住事實 覺得物理雖然難 但是很重要 等等 然後簡短的做個結尾 記住扣住論點
全文要出現一些好詞佳句 可以加分 並且內容要連貫 還有不要總是出現AND AND AND AND這種連詞 要學會用MEANWHILE等詞彙
⑻ 2道英語描述的物理題求助~~~
Problem 4: 3e²/4πε0a。
Problem 3: Infinite。
Problem 4: 先有一個電子e,無需做功。從無窮遠處搬來第二個電子的時候,該電子的電勢變化為e/4πε0a,所以做功為e×e/4πε0a=e²/4πε0a,因此電子相斥,所以是做正功。從無窮遠處搬來第三個電子的時候,電子的電勢變化為e/4πε0a+e/4πε0a=2e/4πε0a,所以做功為e×2e/4πε0a=2e²/4πε0a,為正功。因此一求和,得總功為3e²/4πε0a。
Problem 3: 用積分算。在二維坐標內,設電線方程為y=0(即x軸),而點P(0,r)。從x到x+dx的一小段電線,帶電量為λdx。而距離P的距離為√(x²+r²),因此在P點產生的電勢為λdx/4πε0√(x²+r²),把x從0積到正無窮(然後再算上負軸,把結果乘2),得電勢為無窮大。λ/4πε0√(x²+r²)的原函數為λ/4πε0 × ln(√(x²+r²)+x)。事實上電場強度為2λ/4πε0r,積分求電勢確實也是無窮。
