Explanation:
The correct answer is Alex and Tracy both are correct. Key Points If the Moon has twice the mass that it does, the force between the Earth and the Moon would be twice as large. F= G x (mass of moon ) x (mass of Earth) / distance2 So, if the Moon was twice as massive, the attractive force of Earth on the moon be twice as large and the attractive force of the moon on Earth would be both twice bigger. If the Moon were half the distance from the Earth, the gravitational force would be four times as large F = G x (mass of moon) x (mass of Earth)/ distance2 According to the formula it clearly visible that if the moon were half the distance from the Earth, the gravitational force would be four times as large.
বাংলা সাহিত্য ও ব্যাকরণ হলো বাংলা ভাষার দুটি অবিচ্ছেদ্য অঙ্গ। বাংলা সাহিত্য হলো বাংলা ভাষায় রচিত কবিতা, উপন্যাস, নাটক, গল্পসহ সৃজনশীল ও মননশীল রচনার সমষ্টি, যার সূচনা দশম শতাব্দীতে 'চর্যাপদ' এর মাধ্যমে। অন্যদিকে, বাংলা ব্যাকরণ হলো এমন একটি শাস্ত্র বা বিজ্ঞান, যা বাংলা ভাষার গঠন, প্রকৃতি, ধ্বনি, শব্দ ও বাক্যের নিয়ম-কানুন বিশ্লেষণ করে ভাষার শুদ্ধ রূপ ও প্রয়োগ শেখায়।
